Thread-topic: Incorporating spatial correlation in logistic modeling in S-Plus

Did anyone deal with a need to include spatial correlation into logistic models?

 

I am running logistic regressions to determine significant factors affecting distribution crop yield categories within fields.

The yield observations tend to spatial correlate within fields that validates the assumption that the response variables are independent.

 

There is an  Option in Spatial Regression to consider spatial or covariance structure by building a neighbor grids for ordinary linear regression.

Is it possible to do the same with Logistic Regression?

 

Thanks,

 

Peter
