I am running some Incremental Spatial Autocorrelation analysis on some disease outbreak data for a series of different years. The results are intuitively what I would expect in terms of the distance where I am seeing a peak in each analysis. However, I get ' Warning 001532: * At least one distance increment resulted in features with no neighbours which may invalidate the significance of the corresponding results.' How serious is this if the results look okay? Can it be over looked or does this mean that my output is meaningless? I attempted to create a spatial weights matrix as that was suggested but I'm not sure how I incorporate that into the analysis.
Thank you for any help or advice!
