This function computes the natural logarithm of marginal posterior density of the PP GaSP model with reference prior of inverse range parameter (beta parameterization) after marginalizing out the mean (trend) and variance parameters by the location-scale prior.

The natural logarithm of marginal posterior density with reference prior of inverse range parameter (beta parameterization).
a vector of natural logarithm of inverse-range parameters and natural logarithm of the nugget-variance ratio parameter.
the nugget-variance ratio parameter if this parameter is fixed.
Boolean value of whether the nugget is estimated or fixed.
a list of matrix where the j-th matrix is an absolute difference matrix of the j-th input vector.
the mean basis function i.e. the trend function.
the mean basis function is zero or not.
the output matrix.
type of kernel. matern_3_2 and matern_5_2 are Matern kernel with roughness parameter 3/2 and 5/2 respectively. pow_exp is power exponential kernel with roughness parameter alpha. If pow_exp is to be used, one needs to specify its roughness parameter alpha.
