R2ROC (version 1.0.1)

auc_trf: auc_trf function

Description

This function transforms the observed scale predictive ability (R2) and its standard error (SE) to AUC with its SE

Usage

Value

This function will transform the observed R2 and its s.e between to AUC. Output from the command is the lists of outcomes.

auc

Transformed AUC

se
