Determine the Ideal PCC

Description

Determine the probability of correct classification (PCC) for a study employing the ideal classifier. The ideal classifier is constructed assuming we know exactly the important features and their effect size. The ideal PCC is the uppper bound of the PCC of any linear classifiers.

Usage

ideal_pcc(mu0, m, p1 = 0.5)

Arguments

mu0

The effect size of the important features.

m

The number of the important features.

p1

The prevalence of the group 1 in the population, default to 0.5.

Value

The PCC of the ideal classifier.
