Kernel Density Search Radius

Discussion created by g.hopkins4 on Sep 30, 2013
I've been trying to find advice as how to chose a value to set the 'Search Radius' to when carrying out a kernel density analysis? I am using this to plot density of marine mammals (data points) across an area of roughly 100km². I have come across a couple of pages suggesting using 'Incremental Spatial Autocorrelation' and 'Spatial Autocorrelation' however these will not work on my dataset. I have also seen the advice to simply chose a value relative to what you are trying to show with your data, I understand this however I do not understand how to ensure that this value is appropriate to your data set and scientifically represents your data significantly?
