metaSDTreg (version 0.2.2)

points.predict_roc: Points from predicted ROC curve

Description

Plot points method for objects of class 'predict_roc'.

Usage

# S3 method for predict_roc
points(x, thr = seq(-10, 10, length = 1000), ...)

Value

Invisible.

Arguments

x

A 'predict_roc' object to plot.

thr

The sequence of thresholds parametrising the ROC curve, if this is a function. Default to a length 1000 sequence from -10 to 10.

...

Addtional arguments passed to lines.

Examples

## Declare simulated data as metaSDTdata
metadata <- metaSDTdata(simMetaData, type1='resp', type2='conf', signal='S')

## Fit model to subset of data
fit <- metaSDTreg(A ~ signal,
            data=metadata,
            subset = m <= 20)

## Plot observed type 1 ROC points
plot(predict_roc(metadata, type = '1'), xlim = 0:1, ylim = 0:1, pch = 'x')

## Add Model-predicted ROC curve (estimated from subset of data)
points(predict_roc(fit, type = '1'))
