Detailed Description

Galtier's 2001 covarion model.

This model is a subclass of the so-called Markov-modulated substitution models, with a Jukes-Cantor rate matrix, of parameter $\nu$. the original version uses a discrete $\Gamma$ distribution for rates, but you can use it with virtually any rate distribution.

Returns:
The normalized Markov generator matrix, i.e. all normalized rates of changes from state i to state j. The generator is normalized so that (i) $ \forall i; \sum_j Q_{i,j} = 0 $, meaning that $ $ \forall i; Q_{i,i} = -\sum_{j \neq i}Q_{i,j}$, and (ii) $ \sum_i Q_{i,i} \times \pi_i = -1$. This means that, under normalization, the mean rate of replacement at equilibrium is 1 and that time $t$ are measured in units of expected number of changes per site. Additionnaly, the rate_ attibute provides the possibility to increase or decrease this mean rate.

void bpp::G2001::updateRatesModel ( ) [inline, protected, virtual]

Update the rates vector, generator and equilibrium frequencies.

This method must be implemented by the derived class. It is called by the fireParameterChanged() method.

Implements bpp::MarkovModulatedSubstitutionModel.
