K3Pmodel -- The model corresponging to the Kimura 3-parameter model

Description

The Kimura 3-parameter (K3P) Model is a Markov model of base substitution. It assumes the root distribution vectors describe all bases occurring uniformly in the ancestral sequence. It allows different probabilities of the base changes A-G, A-C and A-T. This is the most general group based model on group (ℤ/2ℤ)2.

The transistion matrix has the form
