ROCplot

Description

Creates a ROC plot.

Usage

ROCplot(model, direction = "auto")

Arguments

model

an object of type model from bimixt.model

direction

same as roc: same as pROC: the direction in which to make the comparison. "auto" (default): automatically define in which group the median is higher and take the direction accordingly. ">": if the values for the control group are higher than the values of the case group (controls > t >= cases). "<": if the values for the control group are lower than the values of the case group (controls < t <= cases).

Value

Plots empirical and model-based estimates of the receiver operator characteristic (ROC) curve. The empirical plot comes from the pROC package.
