Table 1.

Mean absolute errors in the estimated mean, mode, and standard deviation against directly sampling the exact posterior pdf: the presented method (GP-accelerated MH) vs. sampling the GP surrogate pdf only (MH on GP).

Method	Mean	Mode	Standard deviation
GP-accelerated MH	0.012	0.030	0.006
MH on GP	0.039	0.058	0.015
