mlr_measures_surv.calib_beta: Van Houwelingen's Beta Survival Measure

Description

This calibration method fits the predicted linear predictor from a Cox PH model as the only predictor in a new Cox PH model with the test data as the response. $$h(t|x) = h_0(t)exp(l\beta)$$ where \(l\) is the predicted linear predictor.

The model is well calibrated if the estimated \(\beta\) coefficient is equal to 1.

Assumes fitted model is Cox PH.

Dictionary

This Measure can be instantiated via the dictionary mlr_measures or with the associated sugar function msr():
