Really good video. Thanks!

Thanks Jef for this lecture. I have a question. at 21:42 min. when you are explaining the variogram modeling with anisotropy. We agree that total anisotropy has a geometric and zonal components. But Is there any chance that the labels of Y and X directions in the variogram on the right are exchanged? Because it seems to me that along the Y- direction the variance is larger and range is shorter than along the X-direction. Thanks and regards.

yes, it seems that you are right about that.

Question for you or someone in the audience: when using an anisotropic variogram, is it convention to fit ellipsoidal parameters or fix them in advance prior estimating model parameters? Any thoughts are greatly appreciated.
