title: 'powerpkg: Power Analyses for the Affected Sib Pair and the TDT Design'
version: '1.6'
doi: 10.32614/CRAN.package.powerpkg
abstract: '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.'
