REGRESSION METHODS IN BIOSTATISTICS

This new book provides a unified in depth readable introduction to the multipredictor regression methods most widely used in biostatistics linear models for continuous outcomes logistic models for binary outcomes the Cox model for right censored survival times repeated measures models for longitudinal and hierarchical outcomes and generalized linear models for counts and other outcomes Treating these topics together takes advantage of all they have in common The authors point out the many shared elements in the methods they present for selecting estimating checking and interpreting each of these models They also show that these regression methods deal with confounding mediation and interaction of causal effects in essentially the same way The examples analyzed using Stata are drawn from the biomedical context but generalize to other areas of application While a first course in statistics is assumed a chapter reviewing basic statistical methods is included Some advanced topics are covered but the presentation remains intuitive A brief introduction to regression analysis of complex surveys and notes for further reading are provided
