Mean running times (in milliseconds) using a single core of an AMD A12-9730P processor, when generating 2,000 samples of the posterior distribution for the model based on radial functions (our proposal) using both MCMC (MC) and variational (V) methods, for each synthetic dataset under all simulation settings considered in Section 5.
