Statistical Tests for Discrete Cross-species Data

  title={Statistical Tests for Discrete Cross-species Data},
  author={A Gilabert},
Four methods have been proposed that can be used to test for associations between the states of discrete characters in cross-species data and that do not suffer from non-independence due to overcounting of data points. The tests are those of Ridley (1983), Burt (1989), Grafen (1989), and a new test called the ICDE test. The aim of the paper is to measure the Type I error rates for these methods with simulated null distributions of discrete characters. The null data is generated by a model of… CONTINUE READING
