fystar: Conditional posterior distribution of the distict Ystar

Description

This function evaluates the ratio of conditional posterior distributions of the distict latents Ystar.

Usage

rfystar(v, v2, x, distr.k, sigma.k, distr.p0, mu.p0, sigma.p0)

Details

For internal use.

Examples

## The function is currently defined as
function (v, v2, x, distr.k, sigma.k, distr.p0, mu.p0, sigma.p0) 
{
    alpha <- p0(v, distr = distr.p0, mu = mu.p0, sigma = sigma.p0)/
             p0(v2, distr = distr.p0, mu = mu.p0, sigma = sigma.p0)
    Prod <- 1
    for (i in seq(length(x))) {
        fac <- dk(x[i], distr = distr.k, mu = v, sigma = sigma.k)/
               dk(x[i], distr = distr.k, mu = v2, sigma = sigma.k)
        Prod <- Prod * fac
    }
    f <- alpha * Prod
    return(f)
  }
