# mrsprep

The mrsprep command restructures survival data and calculates weighted mean expected mortality rates and time-dependent weights so that a marginal relative survival can be directly estimated. After running mrsprep estimation commands that fit (conditional) relative survival models (e.g. stpm2 or strcs) can be used to estimate marginal relative survival without out the need to include covariates that affect expected survival.

You can install mrsprep within Stata using
