scipy.maxentropy.conditionalmodel.normconst

conditionalmodel.normconst()

Returns the normalization constant, or partition function, for the current model. Warning – this may be too large to represent; if so, this will result in numerical overflow. In this case use lognormconst() instead.

For ‘bigmodel’ instances, estimates the normalization term as Z = E_aux_dist [{exp (params.f(X))} / aux_dist(X)] using a sample from aux_dist.
