One way to create a kriging model is by fitting a variogram and using it to interpolate values at unobserved locations. This process can be visualized using a kriging fitted hat plot, which displays the predicted values at each location based on the kriging model. While this method is effective, there are also other methods of fitting variograms that can be used for kriging. It is important to carefully consider which method to use based on the data and the desired outcome. Additionally, it is important to note that kriging is just one of many spatial interpolation techniques available for geostatistical analysis.
