PVB correction by Begg and Greenes' method 1 (deGroot et al, no covariate)

Description

Perform PVB correction by Begg and Greenes' method 1 as described in deGroot et al (2011), in which it also includes PPV and NPV calculation.

Usage

acc_dg1(data, test, disease, description = TRUE)

Arguments

data	A data frame, with at least "Test" and "Disease" variables.
test	The "Test" variable name, i.e. the test result. The variable must be in binary; positive = 1, negative = 0 format.
disease	The "Disease" variable name, i.e. the true disease status. The variable must be in binary; positive = 1, negative = 0 format.
description	Print the name of this analysis. The default is TRUE. This can be turned off for repeated analysis, for example in bootstrapped results.

Value

A data frame object containing the accuracy results.

Examples

acc_dg1(data = cad_pvb, test = "T", disease = "D")  # equivalent to result by acc_ebg()
