Última Explained variation for survival models AgEcon Royston, Patrick. This article introduces a new measure of explained variation for use with censored survival data. It is a modified version of a measure previously described by John O’Quigley and colleagues, itself a modification of Nagelkerke’s earlier proposal for a general index of determination. I describe Stata programs str2ph, which implements the new measure, and str2d, which implements a measure proposed in 2004 by Royston and Sauerbrei. I provide examples with real data.

Ano: 2006 URL: http://purl.umn.edu/117558 Multiple imputation of missing values: further update of ice, with an emphasis on interval censoring AgEcon Royston, Patrick. Multiple imputation of missing data continues to be a topic of considerable interest and importance to applied researchers. In this article, the ice package for multiple imputation is further updated. Special attention in this article is paid to imputing interval-censored observations, and a suggestion to use imputation of right-censored survival data to elucidate covariate effects graphically.
