Variogram models
================

Scikit-GStat implements different theoretical variogram functions. These
model functions expect a single lag value or an array of lag values as input
data. Each function has at least a parameter `a` for the effective range and
a parameter `c0` for the sill. The nugget parameter `b` is optional and will
be set to :math:`b:=0` if not given.
