Kriging map interpolation in r

WebKriged maps using a variogram with no or a small nugget are typically very similar to inverse distance interpolation results. The lz.ok object stores not just the interpolated … WebWe are going to interpolate (estimate for unsampled locations) the precipitation values. The simplest way would be to take the mean of all observations. We can consider that a “Null-model” that we can compare other approaches to. We’ll use the Root Mean Square Error (RMSE) as evaluation statistic.
