evaluate the probability of a gamma parameter from the probability density function defined by old parameters

1	gammakernel(y, x, z,betas.ini,gammas.now,gammas.old,gpri,Gpri,model,m,ni)

`y`	object of class matrix, with the dependent variable
`x`	object of class matrix, with the variables for modelling the mean
`z`	object of class matrix, with the variables for modelling the variance
`betas.ini`	a vector with the beta that define the old p.d.f
`gammas.now`	a vector with the gamma parameter - new parameters - to evaluate in the old p.d.f
`gammas.old`	a vector with the gamma that define the old p.d.f
`gpri`	a vector with the initial values of gamma
`Gpri`	a matrix with the initial values of the variance of gamma
`model`	it indicates the model that will be used. By default, is the Beta Binomial model (BB), but it could also be the Negative Binomial with mean and shape (NB1) or the Negative Binomial with mean and variance (NB2).
`m`	It is positive integer that In the Beta Binomial model indicates the number of trials. By default, is the number of data
`ni`	It is a vector of positive integer that In the Beta Binomial model indicates the number of trials to each individual. By default, is a vector of m

Evaluate the probability of a gamma parameter from the probability density function defined by old parameters, according with the model proposed by Cepeda(2001) and Cepeda and Gamerman(2005).
