I have to create a number of kernel density layers.  I'm supposed to use the z-score in the calculation.  I do not see an option to enter z-score in the Kernel density tool. Could I use the Population input?  My directions specifically state to create the layers using the z-scores.

Hi Jones

I think my post there provides you an answer to your question
http://forums.arcgis.com/threads/72223-Kernel-or-Point-Density-output-unit-points-per-...-furter-exp...

forgott my question there its useless - arcgis gives the unit you have choosen!

good luck!

I want to display the density of house sells in a city, with a ruster surface. Input data are points - one point per zell.

So for this tool I have found tow video tutorials:
http://video.arcgis.com/watch/401/pe...nsity-analysis
(the hole video)
http://video.esri.com/watch/903/spat...best-practices
(only the first 16 min.)

So I have started with the fowolling steps:
1) Integrate (to summarize the points in a area)
2) Collect events (to get a count field)
3) Calculate Distance Band (as shown in the video spatial best-practices)
4) Calculate the "search radius" - one of the inputs for the density tool
- Load "Incremental Spatial Autocorrelation" toolbox (as shown in the video spatial best-practices)
- Values from Distance Band
Maximum Distance = Beginning Distance
Average Distance = Distance Increment
