Propose a value for posterior distribution of the beta parameter

1	dpostb(y,x,z,betas,gammas,bpri,Bpri,model,m)

`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`	a vector with the previous proposal beta parameters
`gammas`	a vector with the previous proposal gamma parameters
`bpri`	a vector with the initial values of beta
`Bpri`	a matrix with the initial values of the variance of beta
`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

Generate a proposal for the beta parameter according to the model proposed by Cepeda and Gamerman(2005).
