GEIGER: investigating evolutionary radiations

Bioinformatics. 2008 Jan 1;24(1):129-31. doi: 10.1093/bioinformatics/btm538. Epub 2007 Nov 15.


Summary: GEIGER is a new software package, written in the R language, to describe evolutionary radiations. GEIGER can carry out simulations, parameter estimation and statistical hypothesis testing. Additionally, GEIGER's simulation algorithms can be used to analyze the statistical power of comparative approaches.
