Case Studies in Data Analysis by Jane F Gentleman( )

1 edition published in 1994 in English and held by 58 WorldCat member libraries worldwide

The purpose of this volume is to provide some illustrative examples of the analysis of real-world data drawn from areas as diverse as public policy, medical science, meteorology, and market research. For each case, two or more analysts worked independently in a simulated consultancy context. Each case study begins with a description of the questions at hand, the data sets available, and they then present in detail the analysts' solutions and conclusions
Smoothing procedures for simulated longitudinal microdata by Jane F Gentleman( Book )

8 editions published in 1990 in English and held by 36 WorldCat member libraries worldwide

Statistics Canada is adding health characteristics and risk factors to a demographic and labor force model of the Canadian population. This paper describes a method for obtaining multivariate transition probabilities between states for use in advancing individuals in simulated time. The lack of longitudinal data means that these probabilities must be derived from cross-sectional data. The use of transition probabilities by the microsimulation model has the effect of producing smoother, more realistic, logically possible life histories. The probabilities are constrained to maintain consistency with the cross-sectional distributions, and an objective function is chosen to discourage unrealistically large or frequent changes of state over time. The paper uses Canada Health Survey data to generate multivariate transition probability arrays for smoking, blood pressure, cholesterol, and body mass index, all thought to be important risk factors for coronary heart disease
The distribution of the frequency of occurrence of nucleotide subsequences based on their overlap capability by Jane F Gentleman( Book )

5 editions published in 1988 in English and held by 29 WorldCat member libraries worldwide

DNA's genetic code can be represented as an alphabetic sequence composed of the four letters A, C, G, and T, which represent the four types of nucleotides - adnylic, cytidylic, guanylic, and thymidylic acid - of which DNA is composed. Now that these sequences have been identified for many genes and are available in computer-readable form, scientists can analyze these data and search for patterns in an attempt to learn more about the regulatory functions of the gene. One area of study is that of the frequency of occurrence of specific nucleotide subsequences (e.g., ACAC) within part or all of a nucleotide sequence. This paper derives the probability distribution of the frequency of occurrence of a subsequence within a nucleotide sequence, under the hypothesis that the four nucleotides occur at random and with equal probability. This distribution is nontrivial because different subsequences have different "overlap capability". For example, the subsequence AAAA can occur up to 17 times in a sequence of length 20 (which would happen if the sequence were composed solely of A's), but the subsequence ACGT cannot occur more than 5 times in a sequence of length 20. Thus, the frequency distributions are different for each type of overlap capability. It is of interest to assess and compare the degree of nonrandomness for different subsequences or among different portions of a sequence; the existence and degree of nonrandomness may be related to the type and degree of functionality of a nucleotide (sub)sequence. Using the frequency distributions provided here, exact significance tests of the hypothesis of randomness can be performed. An approximate test is also described for use with long sequences; this can be used to test a more general null hypothesis of nucleotides occurring with unequal probabilities
Mainframe SAS enhancements in the support of exploratory data analysis by Statistics Canada( Book )

2 editions published between 1989 and 1992 in English and held by 21 WorldCat member libraries worldwide

This document is a manual describing computer software developed for exploratory data analysis at Statistics Canada. The new software comprises a collection of SAS functions and macros with heavy emphasis on graphics. Together with some functions already available in the SAS system, these routines perform the following types of operations: evaluation of probability density functions (PDF's), cumulative distribution functions (CDF's), and inverse DCF's for nine distributions; calculation of sample quantiles; generation of random numbers; graphing of histograms with optional PDF superimposition; and graphing of Q-Q and P-P plots comparing a sample to any of the nine distributions. Detailed instructions are provided for using the software to construct Q-Q plots comparing two samples

Méthodes de lissage pour microdonnées longitudinales simulées by Jane F Gentleman( Book )

8 editions published between 1989 and 1990 in French and English and held by 13 WorldCat member libraries worldwide

Les modèles de microsimulation permettent d'étudier le comportement de grandes populations dans le temps. À Statistique Canada, on a intégré des caractéristiques de santé et des facteurs de risque à un modèle démographique de la population active canadienne. Dans cet article, nous décrivons une méthode permettant de calculer des probabilités de transition multidimensionnelles utilisées dans la simulation de cycles de vie d'individus. Faute de données longitudinales, on doit se servir de données transversales pour calculer ces probabilités. Un modèle de microsimulation qui utilise des probabilités de transition produira des cycles de vie plus uniformes, plus vraisemblables. Pour qu'il y ait concordance avec les distributions transversales, des contraintes sont imposées aux probabilités. Ces contraintes peuvent être formulées comme celles du problème du transport dans la théorie de la planification par réseaux. Dans ce genre particulier de programmation linéaire, on choisit la fonction objectif de manière à maintenir le degré et la fréquence des changements d'état dans le temps à un niveau raisonnable. À l'aide de données de l'Enquête Santé Canada, nous construisons des tableaux de probabilités de transition multidimensionnelles pour la consommation de tabac, la tension artérielle, le taux de cholesterol et l'indice de masse corporelle, qui sont tous reconnus comme d'importants facteurs de risque en ce qui a trait à l'insuffisance coronarienne
Améliorations apportées au SAS de l'ordinateur central en vue de faciliter l'analyse exploratoire des données by Richard A Johnson( Book )

4 editions published in 1989 in French and held by 13 WorldCat member libraries worldwide

Ce manuel contient la description du logiciel informatique développé à Statistique Canada aux fins de l'analyse exploratoire des données. Le nouveau logiciel comprend une variété de fonctions et de macro-instructions SAS, l'accent étant mis sur le traitement graphique. Ces programmes permettent d'exécuter, en plus de certaines fonctions déjà disponibles dans le système SAS, les types suivant d'opérations: évaluation de la densité de probabilité (DP), fonction cumulative des distributions (FDC) inverse applicable à neuf distributions; calcul des quantiles d'échantillons; production de nombres aléatoires; traitement graphique des histogrammes avec superposition DP optionnelle; calcul des FDC empiriques avec traitement graphique et superposition FDC optionnels et traitement graphique des nuages de points Q-Q et P-P permettant de comparer en échantillon à l'une des neuf distributions. Des instructions détaillées sont fournies sur la façon d'utiliser le logiciel pour établir les nuages de points Q-Q permettant de comparer deux échantillons
Distribution de la fréquence d'occurence des sous-séquences de nucléotides, d'après leur capacité de chevauchement by Jane F Gentleman( Book )

5 editions published in 1988 in French and held by 10 WorldCat member libraries worldwide

Le code générique de l'ADN peut être représenté sous forme d'une séquence alphabétique formée des lettres A, C, G, et T, qui représentent les quatre types de nuclétides qui composent l'ADN: acides adénylique, cytidilique, guanylique et thymidylique. Maintenant que ces séquences ont été identifiées pour de nombreux gènes et qu'on les possède sous une forme qui se prête au traitement par ordinateur, les scientifiques peuvent les analyser et y rechercher des structures, afin de tenter de mieux connaître les fonctions régulatrices du gène. L'un des sujets étudiés est la fréquence d'occurrence de sous-séquences particulières de nucléotides (par ex. ACAC) dans l'ensemble, ou une partie, d'une séquence de nucléotides. Dans le présent document, on établit la distribution de probabilité de la fréquence d'occurrence d'une sous-séquence dans une séquence de nucléotides, dans l'hypothèse où les quatre nucléotides apparaissent au hasard et avec une probabilité égale. La distribution n'est pas triviale puisque des sous-séquences différentes présentent des "capacités de chevauchement" différentes. Par exemple, la sous-séquence AAAA peut exister jusqu'à 17 fois dans une séquence de longueur 20 (ce qui se produira si la séquence est composée seulement de A), mais la sous-séquence ACGT ne peut survenir plus de 5 fois dans une séquence de longueur 20. Ainsi, les distributions de fréquences sont différentes pour chaque type de capacité de chevauchement. Il est intéressant d'évaluer et de comparer le degré d'occurrence aléatoire pour différentes sous-séquences, ou différentes parties d'une sous-séquence; l'existence et le degré d'une occurrence non-aléatoire peuvent être reliés au type et au degré de fonctionnalité d'une (sous-)séquence de nucléotides. Au moyen des distributions de fréquences présentées ici, on peut effectuer des tests de signification exacts de l'hypothèse d'une occurrence aléatoire. On décrit aussi un test approximatif qui convient aux longues séquences; ce test peut servir à vérifier l'hypothèse nulle plus générale selon laquelle les nucléotides se présentent avec des probabilités inégales
Earnings and death-effects over a quarter century by Statistics Canada( Book )

4 editions published in 1990 in English and held by 9 WorldCat member libraries worldwide

This study reports an analysis of male mortality at ages 65 to 74 in relation to employment and self-employment earnings histories during the 10-20 years prior to age 65, as well as marital status, disability, and age at retirement. The analysis is based on administrative data from the Canada Pension Plan, covering more than 500,000 individuals. The results reported include observations of significant mortality gradients throughout the earnings spectrum, which are also clearly evident in a multivariate context. The results illustrate the major potential of administrative data for research and raise important questions regarding pension and health policy
Patterns of divorce in Canada, 1970-1993 by Jane F Gentleman( )

2 editions published in 1996 in English and held by 7 WorldCat member libraries worldwide

This study analyzes 24 years of Canadian divorce data, from 1970 through 1993, focusing on three time periods (1970-72, 1980-82, and 1990-92) and three age groups (15- 29, 30-64, and 65-87). Information not previously available is provided about divorce at older ages. Also, newly-available counts of the legally married population are used to provide a more precise picture of trends in divorce rates. The results show that, except for a peak in 1987 after liberalization of divorce laws in 1985, the general trend over the 24 years has been for the divorce rate to increase gradually, with rates in recent years vacillating relatively slightly. Divorce rates increase with age from 15 to about 29, and then decrease with age. For people in the oldest age group, marriages ending in divorce last either a short time (2 years for men in 1990-92) or a long time (42 years). The probability of getting a divorce, given that the marriage has already lasted a certain number of years, increases rapidly for the first few years after marriage, peaking at five years and decreasing thereafter

Chirurgie des anévrismes de l'aorte abdominale : différences selon le sexe by Greg F Parsons( )

2 editions published in 1997 in French and English and held by 2 WorldCat member libraries worldwide

This article analyzes abdonminal aortic aneurysm (AAA) surgery rates by sex for inpatients of Canadian hospitals. Possible reasons for the observed gender differences in surgery rates are discussed. For fiscal years 1983/84 to 1993/94, over 100,000 hospitalization records for patients aged 45 and over with an AAA were extracted from the Hospital Morbidity File maintained by Statistics Canada. Surgery rates were calculated by sex for hospitalizations involving non-ruptured and ruptured AAAs. To control for sex differences in AAA prevalence and hospitalization rates, surgery rates were based on the population of hospital inpatients with AAA. Rates of elective and emergency AAA surgery were consistently and substantially lower for women than men. Gender differences in AAA prevalence, hospitalization rates, age, and contraindications for surgery cannot explain the differences in surgery rates between women and men. Possible gender bias in the decision to operate could not be ruled out
