✦ Synopsis

A method is described for compacting homogeneous and separating heterogeneous data subcomponents. Allowance is made for heterogeneity due to a concomitant variable. When used with a large sample size, the major component of bivariate normal data wiU tend to be compacted to a single point. By applying the algorithm twice, the major component of bivariate lognormal data will tend to be compacted to a single point. These procedures have been implemented as part of an interactive graphical system for convenient use by biomedical researchers.

We introduce the subpopulation treatment e ect pattern plot (STEPP) method, designed to facilitate the interpretation of estimates of treatment e ect derived from di erent but potentially overlapping subsets of clinical trial data. In particular, we consider sequences of subpopulations deÿned with r
