Four compilations of medical library statistics have been published to date, namely those by Louise Darling in 1956, by the Medical Library Association in its 1959 Directory, by Harold Bloomquist in 1962, and by the author in 1964. In addition to these sources and to the annual s...

The Annual Statistics of Medical School Libraries in the United States and Canada (Annual Statistics) is the most recognizable achievement of the Association of Academic Health Sciences Libraries in its history to date. This article gives a thematic history of the Annual Statisti...

We have compared the power of a large number of allele-sharing statistics for “nonparametric” linkage analysis with affected sibships. Our rationale was that there is an extensive literature comparing statistics for sibling pairs but that there has not been much guidance on how t...

We have compared the power of several allele-sharing statistics for “nonparametric” linkage analysis of X-linked traits in nuclear families and extended pedigrees. Our rationale was that, although several of these statistics have been implemented in popular software packages, the...

The learning of Statistics has become increasingly important to the success of companies which compete in global scenarios and has highlighted the professionals who, in fact, have this knowledge. In particular for the business administration, statistics assists in the decisionmak...

Scan statistics are applied to combine information on multiple contiguous genetic markers used in a genome screen for susceptibility loci. This information may be, for example, allele sharing proportions for sib pairs or logarithm of odds (lod) scores in general small families. W...

In this work, several simulated annealing algorithms presented in the literature as solutions to different problems were compared in the scheduling of multiproduct serial batch plants. A systematic performance study of the original algorithm, based on the Boltzmann statistics, an...

Abstract Statistics has been incorporated in most university courses and among them in the degree of Psychology, where the teaching of statistical concepts presents specific learning problems, because students enrolled have a very heterogeneous mathematical basis. In this work, w...

Spatial structure of genetic variation within populations, an important interacting influence on evolutionary and ecological processes, can be analyzed in detail by using spatial autocorrelation statistics. This paper characterizes the statistical properties of spatial autocorrel...

Common statistical analyses were applied to the statistics on medical school libraries published in 1964 and 1966 in the Bulletin to assess the potential utility of such survey data. The major conclusions of the study are that these statistics (1) are highly redundant; (2) are es...

We provide an overview on superstatistical techniques applied to complex systems with time scale separation. Three examples of recent applications are dealt with in somewhat more detail: the statistics of small-scale velocity differences in Lagrangian turbulence experiments, trai...

There are many options in handling microarray data that can affect study conclusions, sometimes drastically. Working with a two-color platform, this study uses ten spike-in microarray experiments to evaluate the relative effectiveness of some of these options for the experimental...

A large microsatellite data set from three species of bear (Ursidae) was used to empirically test the performance of six genetic distance measures in resolving relationships at a variety of scales ranging from adjacent areas in a continuous distribution to species that diverged s...

Kappa statistics are widely-used to assess performance in quality assurance schemes. Low values, however, are difficult to interpret, especially when confidence intervals have not been calculated. A model of a dichotomous decision in pathology (benignancy or malignancy in fine ne...

We consider the issue of performing accurate small-sample likelihood-based inference in beta regression models, which are useful for modeling continuous proportions that are affected by independent variables. We derive Skovgaards (Scandinavian Journal of Statistics 28 (2001) 3-32...

Statistics is increasingly used in all fields of medicine but is often poorly understood and incorrectly applied. Critical Care is therefore launching a series of articles aimed at providing a simple introduction or refresher to some of the more commonly used statistical tools an...

This annotated list is a guide to government and nongovernment sources of population, vital, and health statistics. It is arranged first geographically, giving sources for local, regional, state, national, and international statistics, and secondly by issuing body. Below the nati...

During the winter of 1965/66, statistics on library staff, clientele, resources, expenditures, salaries, and services of medical, dental, pharmacy, osteopathic, and public health schools were collected by the MLA Committee on Surveys and Statistics. In an attempt to provide stand...

Classifcation and clustering of time series are problems widely explored in the current literature. Many techniques are presented to solve these problems. However, the necessary restrictions in general, make the procedures specific and applicable only to a certain class of time s...

For a dioecious diploid population subdivided into an arbitrary number of subpopulations, we have derived recurrence equations for the inbreeding coefficient and coancestries between individuals within and among subpopulations and formulas for effective size and F-statistics. Sta...
