Fig. 3: Model fit assessment graphs for the Papua New Guinea application.

The correlation assessments between the observed data and the predicted population counts based on the proposed TSBHM approach at both the census unit and the district levels indicated good predictive ability of the model. A Scatter plot of observed counts vs TSBHM predicted counts with 95% credible intervals (vertical grey lines) across census units. B Density scatter plot with contour lines of observed versus TSBHM predicted counts at the district level.
