I have a geostatistical data. For analysis, I am using `geoR`. I want to estimate the parameters. But `likfit` or `variofit` function requires initial values for the covariance parameters: \(\sigma^2\) (partial sill) and \(\phi\) (range parameter).
But I can't guess the initial values for my data set.
How can I specify the initial values?
