I think the ultimate goal of the assignment is to show those 3 different maps (like the examples at bottom) with different weighting combinations. The one on the right is obviously the best weight.
This is the final step in my instructions:
You will end up with three different maps, which should be standardized from 0 (low KDE value) to ~1 (high KDE values). What you want to do next is to combine the maps together, using different weighting schemes. For instance, for the map that uses the largest bandwidth, if you end up giving a high weight, you will have a blurry map that is not very revealing. Try different weighing combination (see below).
