Abstract: stbtcalc calculates local estimates of the regression coefficients in the Cox model defined by stset with predictors in varlist. The estimates are calculated within moving windows which bracket a fixed number of "deaths" (events). stbtplot plots the estimates and confidence intervals against the failure times. varlist is (a subset of) the predictors in stbtcalc's varlist.
