padjust: Adjust probabilities by a bias factor

In rplzzz/CovMitigation: COVID-19 infection model for Virginia

Description

Given a vector of probabilities and a bias factor (or vector of bias factors), compute the new probabilities adjusted for the bias factor.

Usage

padjust(p, b)

Arguments

p	Vector of probability values
b	Bias factor

Details

The bias factor acts as a multiplier on the odds ratio, so

\frac{p'}{1-p'} = b \frac{p}{1-p}.

Thus, for example, if p=0.1, the odds ratio is r=1/9. A bias factor of 10 would produce r'=10/9, for an ajusted probability of p' \approx 0.53.
