Accommodating covariates in receiver operating characteristic analysis dating law offender sex
The tie-corrected PV for a case with the marker value y_i is the proportion of control values Y_Db character string specifying how the covariate adjustment is to be done: "stratified" (default), "linear", "oprobit" (ordered probit), or "ologit" (ordered logit).
If "stratified", PVs are calculated separately for each stratum defined by is.
Bootstrap standard errors and confidence intervals (CIs) for the requested statistics and marker differences are calculated. Wald test results for marker comparisons are based on the bootstrap standard errors for the difference between markers.
A companion program for the Stata software package is available.
