Table 2.
Simulation study results for model fit. The data-generating scenarios are given in Section 4.1. We compare the full model (“Full”), the model without a nugget term (“No nugget”), the model without the generalized propensity score (“No PS”) and the model without spatial dependence (“Non-spatial”). Estimation of the log mean is measured using the correlation between the true and estimated and empirical coverage of 90% intervals. All values are multiplied by 100 and standard errors are given in subscripts.
