Sample_sigma_2_theta_m_no_discrepancyR Documentation

Sample the variance and mean parameters with no discrepancy function.

Description

This function samples the variance and mean parameters assuming no discrepancy function.

Usage


Sample_sigma_2_theta_m_no_discrepancy(param,  output,   p_theta,   
                                      X,  have_mean, inv_output_weights, cm_obs,
                                      S_2_f,num_obs_all)

Arguments

param

Current parameters in the MCMC.

output

Experimental observations.

p_theta

Number of calibration parameters.

X

Number of mean discrepancy parameters.

have_mean

Whether the mean discrepancy is zero or not.

inv_output_weights

The inverse of the weights of outputs..

cm_obs

outputs from the mathematical model.

S_2_f

Variance of the data. This term is useful when there are repeated experiments.

num_obs_all

Total number of observations. If there is no repeated experiment, this is equal to the number of observable inputs.

Value

A vector of samples of the variance and trend parameters.
