I am trying to determine the level of spatial autocorrelation in a point dataset. The attribute I'm interested in is binary (presence/absence of a species), for which Moran's I is not appropriate. On the other hand, Joint Count statistics, which are typically recommended for binary or categorical data, apparently are not appropriate for point data. In short, the question is thus: what is an appropriate statistic to measure global and/or local spatial autocorrelation of points when the attribute of interest is binary?
