Correlation-Adjusted Regression Survival Scores
Description
Contains functions to estimate the Correlation-Adjusted Regression Survival (CARS) Scores.
The main function is carSurvScore, which estimates CARS scores of each variable.
The higher the absolute values of CARS scores, the higher the variable importance.
Additionally there is the function carVarSelect to select cut-off thresholds
to separate variables associated with survival from noise variables. There are two possible
cut-off threshold options: False non-discovery rate q-values and empirical quantiles of the
raw scores.
