st: Cox Competing Risks Model (Cox CRM)

[Stefan Göke <stefan.goeke@whu.edu>]

Dear statalisters,

I am aware that a competing risks can be implemented e.g. via a separate Cox models or via augmenting the data before applying a Cox model. 

Reading “He et al. (2010) A Competing Risks Analysis of Corporate Survival in Financial Management” and “Dickerson et al. (2003) Is attack the best form of defence? A competing risks analysis of acquisition activity in the UK in Cambridge Journal of Economics”, I am curious to know whether somebody on the list knows how to implement those models in Stata. In fact, the authors present results for three competing risk types where each covariate has a separate coefficient per risk type. However, LL, Chi2 are only presented once, implying that it is only one model the authors estimate. The only way I know to do this is via three separate models that would have one LL, Chi2 etc. each.

Here is an excerpt of table 4 p. 1713 from He et al (2010) to illustrate my question. Their three risk types are bankruptcy, M&A, privatized. –LL is only reported once.
