Subpopulation Treatment Effect Pattern Plot (STEPP) R package stepp version 3.2.7 CRAN Task View: CausalInference (https://CRAN.R-project.org/view=CausalInference) A method to explore the treatment-covariate interactions in survival or generalized linear model (GLM) for continuous, binomial and count data arising from two or more treatment arms of a clinical trial. A permutation distribution approach to inference is implemented, based on permuting the covariate values within each treatment group.
