mukernel {Bayesiantreg} | R Documentation |
the probability of a beta parameter from the probability density funcion defined by old parameters
Description
evaluate the probability of a beta parameter from the probability density function defined by old parameters
Usage
mukernel(y, x, z, betas.now, betas.old, gammas.ini, gl.ini, bpri, Bpri)
Arguments
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.now |
a vector with the beta parameters - new parameters - to evaluate in the old p.d.f |
betas.old |
a vector with the beta parameters that define the old p.d.f |
gammas.ini |
a vector with the gammas parameters that define the old p.d.f |
gl.ini |
a vector with the degrees of freedom parameter that define the old p.d.f |
bpri |
a vector with the initial values of beta |
Bpri |
a matrix with the initial values of the variance of beta |
Details
Evaluate the probability of a beta parameter from the probability density function defined by old parameters, according with the model proposed by Cepeda(2001) and Cepeda and Gamerman(2005).
Value
value |
a matrix with the probability for the beta parameter from the probability density function defined by old parameters |
