stpm3

stpm3 fits flexible parametric survival models. These models use splines to model the effect of the time scale. stpm3 replaces stpm2, though stpm2 will continue to be available on SSC.

I have added some examples to explain some of the features of stpm3 and differences to stpm2.

Installing You will need to install the stpm3, standsurv and gensplines packages. You can install from within Stata from SSC using the code below. If you have already installed earler test versions from my website then I recommend first removing these versions using ado uninstall before installing the version from SSC. Stata does not always refresh the mata libraries when using ado update, so I suggest restarting Stata after updating.

ssc install stpm3
ssc install standsurv
ssc install gensplines
