%description
There are two main functions: (1) To estimate the power of testing for
linkage using an affected sib pair design, as a function of the recurrence
risk ratios. We will use analytical power formulae as implemented in R.
These are based on a Mathematica notebook created by Martin Farrall. (2)
To examine how the power of the transmission disequilibrium test (TDT)
depends on the disease allele frequency, the marker allele frequency, the
strength of the linkage disequilibrium, and the magnitude of the genetic
effect. We will use an R program that implements the power formulae of
Abel and Muller-Myhsok (1998). These formulae allow one to quickly compute
power of the TDT approach under a variety of different conditions. This R
program was modeled on Martin Farrall's Mathematica notebook.
