Thanks to Kit Baum, a new command, -igencox-, is now available on SSC. The
-igencox- command fits non-proportional hazards survival models using
logarithmic or Box-Cox transformations via the EM algorithm described in Zeng
and Lin (2006, 2007). Stata 12 is required.
-igencox- can be installed from a web-aware Stata by typing
. ssc install igencox
