Good day
Currently we are using Pyrige on our project. We use variogram model gaussian, because we are not sure why on linear, all of value in asc are same. On gaussian, the result is fine, but we ne…
I have observed in some cases the CRAVA estimated too long wavelet than what we expected. The default wavelet length in CRAVA is 200ms. And the CRAVA estimated wavelet should usually be close to 200ms…
The current variogram estimation is sensitive to outliers. It would be good to implement the method described by http://www.stat.tamu.edu/~genton/1998.G.MG.1.pdf
