logpriors: Calculate the log prior used in the log marginal density of Chib (1995).

Description

Log marginal likelihood = Log likelihood + Log prior - Log density

Usage

logpriors(h2, data_x, prior_p, prior_st)

Arguments

h2

Square of re-parameterized bandwidths and square of normal error variance

data_x

Regressors

prior_p

Hyperparameter used in the inverse-gamma prior

prior_st

Hyperparameter used in the inverse-gamma prior

Value

• Value of the log prior

Details

Calculate the log prior using the estimated averaged bandwidths of the regressors and the estimated averaged variance of the error density, obtained from the MCMC iterations
