Geographically Weighted Regression with Point Data

Hello all,

I am working on a project that looks at the average charges and reimbursements that hospitals charge Medicare. I've done a spatial clustering analysis on the hospital locations, but would like to bring in other variables about the patient demographics at the hospitals. For example, I'd love to be able to look at if hospitals that treat a higher proportion of older patients (>85 years old) charge more, and if hospitals that treat sicker patients (I have Medicare data on the average "risk score" of patients at each hospital) charge more. Is it appropriate to do a geographically weighted regression with point data? I have done an OLS regression and the standardized residuals are spatially autocorrelated.

I'd appreciate your help!
