i'm not really experienced in spatial stats yet, but i'm growing into it.
I basically want to ascertain if certain values in a raster are a) autocorrelated and b) are more likely to exist in a certain spatial area (k-means? i'm unsure)
the data is a single raster showing land use change from 1 year to another (sorry I can't post the data) and there are about 50 possible changes (some far more prevalent than others). Quickly viewing the raster, it is clear that some changes are more prevalent in northern extremes, some in areas of upland farming etc etc, patterns do exist. But I want to prove this with stats.
For a) Local Moran's I (using a simple binary queen's spatial-weights matrix) gives us indication of spatial autocorrelation - this is useful for finding 'clumps' of similar data, correct?
For b) I'd like to explore whether each change combination is more likely to exist in a certain part of the UK (in Scotland, in western extremes etc). Would this be some sort of k-means clustering?
I'm doing all this in R,
