better Barnet

This seems to overlap better. I have developed a program for counting the overlap, and the distance from the centroid of the given amdin region to the red point in the diagram, which is the "peak".

new adaptive method

I had problems with the adaptive kde just mentioned. It did not work well on the results of the questionaire. I have changed it further and will now re-run it on the regions. the older one seems to have worked well on the regions, probably because the density of points is fairly uniform. The questionaire results are based on very few points (because we had to ask people whether places were in or out of a region). Not sure whether to use the new or the nearly new kde. It is questionable whether to adapt the bandwidth or the "height" of the points.

Also today will be looking at the relationship between distance and size of region in more detail.

A county

I have created an adaptive kde that takes account of frequency. I have thresholded this such that a region of the same area as the known region is created. For Bedforshire it is pretty close. I am now investigating measures of overlap, which I expect will be similar to those for showing potential error in circle model and in using street bounding boxes to define regions.

A region!
