drgegggne {IFP}

causal models with all possible causal factors: G, G*G, G*E and E

Description

provides concordance probabilities of relative pairs for a causal model with G, G*G, G*E and E components

Usage

 drgegggne(fdg,frg,fdgg,frgg,fdge,frge,eg,e)

Arguments

fdg

an array (size=number of dominant genes+recessive genes) of dominant gene frequencies including 0 values of recessive genes of G component

frg

an array (size=number of dominant genes+recessive genes) of recessive gene frequencies including 0 values of dominant genes of G component

fdgg

an array (size=number of dominant genes+recessive genes) of dominant gene frequencies including 0 values of recessive genes of G*G component

frgg

an array (size=number of dominant genes+recessive genes) of recessive gene frequencies including 0 values of dominant genes of G*G component

fdge

an array (size=number of dominant genes+recessive genes) of dominant gene frequencies including 0 values of recessive genes of G*E component

frge

an array (size=number of dominant genes+recessive genes) of recessive gene frequencies including 0 values of dominant genes of G*E component

eg

a proportion of population who are exposed to environmental cause of G*E interactiong the genetic cause of G*E during their entire life

e

a proportion of population who are exposed to environmental cause during their entire life

Value

matrix of NN, ND, and DD probabilities of 9 relative pairs: 1:mzt,2:parent-offspring,3:dzt,4:sibling,5:2-direct(grandparent-grandchild),6:3rd(uncle-niece),7:3-direct(great-grandparent-great-grandchild),8:4th (causin),9:4d(great-great-grandparent-great-great-grandchild)
