      @MartinKulldorff What are your thoughts on Flexscan vs elliptical clusters in @SatScan? It's more challenging to prep data for Flexscan.

      @PaulLantos All work well. Circular scan has slightly more power for compact; elliptic for elongated; and flex for small ragged clusters.

      @PaulLantos With any scan, borders are uncertain. Flexible & elliptic are better able to delineate borders for irregular shaped clusters...

      @PaulLantos ... but they are also more prone to over fitting due to cherry picking, especially for data with fine spatial resolution.
