I want to calculate Moran s I for a grid-based fire severity data set. Within the burned, contiguous area, we have 1 = low severity to 4 = high severity. TheMessage 1 of 1 , Feb 23, 2004View SourceI want to calculate Moran's I for a grid-based fire severity data set.
Within the burned, contiguous area, we have 1 = low severity to 4 =
high severity. The objective is to assess the distance within which
neighbor cells affect a grid cell.
Now, the problem with the unburned area outside the burned area arises.
If I arbitrarily fix an outer boundary and include the grid cells with
unburned area and code them as 0, the area consists of about 25% burned
and 75% unburned area. However, the calculated Moran's I increases
strongly compared to when the unburned area is excluded from the
How would you proceed in such a case, including or excluding the
