A list of 4 elements. The first is a vector for predictive mean for testing inputs. The second is a vector for lower quantile for 95% posterior credible interval and the third is the upper quantile for 95% posterior credible interval for these testing inputs. The last is a vector of standard deviation of each testing inputs.
