Hi
I am looking for some help using the 'optimised hot spot analysis' tool. I havent used this before but from discussions online it looked pretty easy. I have a file with a set of points showing home locations of staff. I would just like a hot spot map showing red where there are clusters of people living etc.
When I use the tool I get an the error message I have attached.
I have attached the shapefile too.
Any help is greatly appreciated!
