https://communities.sas.com/t5/Statistical-Procedures/Modeling-residuals-from-GENMOD-link-logit-dist-binomial-in/m-p/31545#M1288 Hello. I'm wondering if modeling the residual spatial structure for a binary response using these PROCs is "appropriate." Want to use Moran's I to test (under random assumption) for spatial autocorrelation in a binary response, modeled as a function of covariates + trend surface. Any thoughts would be appreciated. Cheers!

GENMOD does not have any spatial covariance structures to choose from.<BR /> <BR /> However, you could use the GLIMMIX procedure to model the residual covariance structure. GLIMMIX fits models from the exponential family so it is appropriate for fitting a logistic regression for a binary response. Also, the GLIMMIX procedure does allow a full set of spatial covariance structures.
