find.prob.rec: Recessive probability finding function

In genpwr: Power Calculations Under Genetic Model Misspecification

Description

Operates within add.or.function to find probability of disease in a recessive truth given AB or BB, additive test model

Usage

find.prob.rec(x, P_AA, P_AB, P_BB, cr, like)

Arguments

x	Probability of disease given AB or BB
P_AA	Probability the allele is homozygous for the major allele
P_AB	Probability the allele is heterozygous
P_BB	Probability the allele is homozygous for the minor allele
cr	proportion of cases in the sample (cases/(cases + controls)).
like	Expected log likelihood

Value

: The "a" in the binomial function ax^2 + bx + c that arises in solution for the additive OR functions

Examples

find.prob.rec(0.7072381, 0.5625, 0.375, 0.0625, 0.3, -0.6005743)
