It might be challenging to accumulate suitable sample measurements in DMUs with number of total square miles or a big proportion of urban and suburban land types.
Sample dimensions for a few of the inputs of your SAK formula are confined. For that reason, it's important to pool details more than several DMUs and/or a long time to generate once-a-year deer populace estimates for all DMUs.

The spatial smoothing model works by using splines to account for correlation in between neighboring DMUs and similarities by zone variety (i.e., Forest, Farmland).
