You are fairly limited here. The two common pattern/autocorrelation statistics appropriate for binary data are the "General Cross-Product Statistic" or the "Joint-Count Statistic". Unfortunately, these are not available in ArcGIS. Here is a nice introduction to these statistics: http://www.stat.ncsu.edu/people/fuentes/courses/madrid/lectures/areal2.pdf There is a Bernoulli specification of the SaTScan statistic but it can be a bit tricky to implement correctly. http://www.satscan.org/papers/k-cstm1997.pdf Thank you Jeffrey, for suggesting an alternative. ArcGIS never tells us what underlying assumptions of these methods are. I will explore SaTScan. Best

I have gathered point data in a cross sectional survey of households which tells you the presence and absence of disease in each households without telling you how many disease cases occur. The idea is to measure households with a burden which is not necessarily translated to disease counts. I want to explore the spatial patterns of these burdens but from what I see of Moran's I or Getis and other spatial statistics tool in ArcGIS, they only deal with continuous data and not favourable for binary presence absence data. The question I want to answer is "Where are there clusters of disease burdened households?" is this a possibility with a sample of 435 households in a cross sectional survey? Could you please advise me if at all I am missing something out on ArcGIS that I could do with my data or if another software/method can deal with my type of data. Thanks in advance

Is binary logistic regression in ArcGIS a possibility ? I know one can do linear regression but binary response regression is what am not sure of. Because I have this sort of data which is also mapped so am wondering what I can do with it in ArcGIS.

hello, I have malaria data at hospital level for 20 hospitals on a monthly basis over a period of 10 years. I will like to do some hotspots in space and time but I haven't a clue of where to start even with arranging my data because I have the data separately from the georeferenced hospital database. If I succeed in doing the database, where can I start with the hotspot analysis? is there a possibility to do it in space and time with point data? Txs
