class stilt.observations.VariogramFit(sigma: 'float', length: 'float') → None[source]#

Exponential variogram σ² (1 − exp(−h / l)).

sigma is the error standard deviation (the square root of the sill) and length the e-folding correlation scale, in the units of the separation it was fitted over. Call it with separations to evaluate the model.
