| Subject | st: multiple imputation and flexible parametric survival models |
| Date | Fri, 19 Jul 2013 01:39:37 -0400 |
Dear listers, I was wondering if someone could shed light on this issue: after multiple imputation, is there a conceptual issue with using -mi estimate, cmdok- with the -stpm2- module (available from ssc) for flexible parametric survival models? In the widely cited article (White IR, Royston P, Wood AM.Multiple imputation using chained equations: Issues and guidance for practice.Stat Med. 2011 Feb 20;30(4):377-99. doi: 10.1002/sim.4067) there is a mention of potential fractional polynomial in the outcome model after -mi-. However I am not sure if the fact that FPM's fit splines differing in each imputation would make Rubin's rules problematic. I would greatly appreciate some insight.
