Converts a survival-analysis data frame from "wide" format, in which time-varying covariates are separate variables, one per occasion, to "long" or counting-process format in which each occasion is a separate row in the data frame.
This dialog box permits you to define a time variable (or start and stop variables), an event indicator, a strata variable or variables, and a cluster variable to be associated with the current data set. If these characteristics are defined, then they will become default choices where appropriate in other dialog boxes.
An R Commander plug-in for the survival package, with dialogs for managing survival data (this to a limited extent), Cox models, parametric survival regression models, estimation of survival curves, testing for differences in survival curves, and a variety of diagnostics, tests, and displays.
