pfc.sim: Probability of familial clustering of disease

In gap: Genetic Analysis Package

Probability of familial clustering of disease

Description

Probability of familial clustering of disease

Usage

pfc.sim(famdata, n.sim = 1e+06, n.loop = 1)

Arguments

famdata	collective information of sib size, number of affected sibs and their frequencies.
n.sim	number of simulations in a single Monte Carlo run.
n.loop	total number of Monte Carlo runs.

Details

To calculate probability of familial clustering of disease using Monte Carlo simulation.

Value

The returned value is a list containing:

• n.sim a copy of the number of simulations in a single Monte Carlo run.

• n.loop the total number of Monte Carlo runs.

• p the observed p value.

• tailpl accumulated probabilities at the lower tails.

• tailpu simulated p values.
