I have a set of raster area results, that represent a prediction for a specific loccation. I would like to measure accuracy of two methods, given the actual values, estimate-A method values and estimate-B method values.
At the moment, for each raster pixel, I'm getting the difference abs(ActualLayer.pixel.value - EstimateLayerA.pixel.value), and using the average difference for a given area as a measure of accuracy (closer to 0 would be better).
This is ok, but are there better methods to quantize the accuracy of estimates against the actual for a given area?
