Multilevel mixed effects parametric survival models

Latest release v2.2.1

The stmixed package began as the accompanying Stata implementation for the methodology developed in:

Crowther MJ, Look MP, Riley RD. Multilevel mixed effects parametric survival models using adaptive Gauss-Hermite quadrature with application to recurrent events and individual participant data meta-analysisStatistics in Medicine 2014;33(22):3844-3858.

stmixed has now grown (and in someways shrunk) to become a wrapper function for merlin, which gives it a lot more capabilities. The new developments in stmixed are now described in a recent Stata Journal paper:
