Get the values of variogram estimator for given lags #181

Closed IAGO1215 closed 4 months ago

IAGO1215 commented 4 months ago

After going through the documentation, I couldn't figure out how to get the values of variogram estimator (Matheron for example) for given lags. There are residuals, RMSE ... functions available so I believe I must have missed sth.

For example, I would like to get the semivariance value of variogram estimator at the lag equal to the range of the spherical variogram model.

Are we talking about the empirical semi-variance value for the lag that contains the effective range or the value modeled by the fitted model at the effective range?

Both is possible, I tried to illustrate both options in the colab below:

Let me know if that was helpful.
