Additional file 2 of Modelling the impact of MAUP on environmental drivers for Schistosoma japonicum prevalence

Additional file 2: Text S1. Code for the convolution model used in OpenBUGS. It includes the prior distributions used for the covariate and spatial parameters and the model itself. The model uses two indexes, k for the barangay and j for the number of city pixels within barangays. The betas are the individual-level regression coefficients, m is the number of city pixels in a barangay. Covariates are ndvi: normalized difference vegetation index, ndwi: normalized difference water index, lstd: land surface temperature day, lstn: land surface temperature night, e: elevation, ndwb: nearest distance to water bodies. The spatial parameter is represented as s.
