Gaussian process emulator for (a) HIV, (b) Hypertension, (c) Comorbid HIV & Hypertension and (d) Depression in Kenya

At each year, black dots represent the selected design points used to fit the emulator, the blue curved lines represent the predicted 95% uncertainty intervals for each design point, the dashed red lines are the mean prevalence for a given year plotted as a function presenting the emulator’s predictions and the yellow thick lines outside are the 95% confidence intervals for the original simulators. Sub-plot D does not include the 95% confidence intervals for the simulator because these data were unpublished
