UserDefinedLikelihood

class cuqi.likelihood.UserDefinedLikelihood(dim=None, logpdf_func=None, gradient_func=None, geometry=None, name=None)

Class to wrap user-defined likelihood functions.

Parameters:

• dim (int) – Dimension of the likelihood.

• logpdf_func (callable) – Function evaluating log density function.

• gradient_func (callable) – Function evaluating the gradient of the log density.

• geometry (Geometry) – Geometry of the likelihood.
