https://communities.sas.com/t5/Statistical-Procedures/Proc-KDE/m-p/69435#M3358 I have been using PROC KDE successfully for quite some time for geospatial analysis, but recently received an error while processing the BIVAR statement: <BR /> <BR /> Error: LATITUDE has too small of a range or the grid size is too large<BR /> <BR /> I am using a max and min latitude as well as longitude for the BIVAR statement. I have adjusted the NGRID value up and down as well as the latitude range, always resulting in the same error.<BR /> <BR /> Does anyone have any insight into this error?

The range error was referring to the data itself--it appears for some datasets, all of the coordinates (latitude and longitude) are the same. Proc kde apparentle requires a range of different coordinates in order to function properly.
