I have a dataset with approx 1250 geolocated points - approx 150 are cases of a disease and the rest are controls. My area of interest is around 20km by 20km with wide variation in population density. I would like to display prevalance (cases/(cases+controls)) as either a kernel density layer or using contours. I would like to use a 3km Gaussian kernel.
Are there plug-ins that can do this?
I couldn't see how to do this in Heatmap.
