WeightCalibSurvival R Package

Description

To improve efficiency for estimating pure risks from additive hazards and Cox proportional hazards models with nested case-control designs.

Details

Methods in this package are applicable to studies with some covariates that are only available for case-control samples nested in a cohort. More efficient estimates of pure risks are obtained by calibrating the design weights to data available in the entire cohort. Variance estimates for the weight-calibrated estimates are based on explicit formulas developed in the references below.
