Understanding Spatial Autocorrelation in Mixed-Effect Models: When to Use Moran's I Test or Spatial Weight Matrix
Understanding Spatial Autocorrelation in Mixed-Effect Models Background and Introduction Spatial autocorrelation is a common phenomenon in geospatial data where the values of a variable are not randomly distributed across space. This means that nearby observations tend to be similar, either because they share environmental conditions or because of other spatial structures. In the context of ecological or biological studies, spatial autocorrelation can lead to biased estimates if not properly accounted for.
