CH 4: Illustrations for weights

[iamwfx]

• I really appreciate the kernel weights illustration you have of San Diego showing the weights for the 1st and 18th tracts. For my lecture, I copied the charts to illustrate the differences between fixed bandwidth and the binary vs continuously weighted distance bands. I found the "distance bands and hybrid weights" section especially tricky to wrap my head around.

• Also, again very minor, but creating block weights from the san diego tract dataset, where you are blocking by county, but there is only one county, might also be a little confusing. But again, all this in the context me thinking through the text for students very new to these concepts!
