stilt.observations.fit_variogram(lag, gamma, *, sigma=None)[source]#

Fit an exponential variogram to an empirical one.

Parameters:

  • lag (TypeAliasType) – The empirical variogram, as returned by variogram().

  • gamma (TypeAliasType) – The empirical variogram, as returned by variogram().

  • sigma (float | None) – Error standard deviation. When given, the sill is fixed at sigma² and only the correlation scale is fitted, as Lin and Gerbig’s definition implies. Use it when the sample standard deviation is known. None fits both.

Return type:
