class Taweret.sampler.likelihood_wrappers.likelihood_wrapper_for_bilby(mixed_model, x_exp, y_exp, y_err)[source]

Bases: Likelihood

Likelihood wrapper for Bilby calibrator ...

mixed_model

mixed model object from Taweret model mixing class

Type: object

parameters

dictionary with name of each parameter to be given to Bilby. all parameters have the prefix theta_ and then the parameter number. ex : for liklihood with three free parameters ; theta_0, theta_1, theta_2 Parameters are order as [mixture function parameters, model 1 parameters, model 2 parameters]

Type: dic

log_likelihood(self)[source]: calculates the log likelihood for the parameter values specefied in the wrapper object.

Empty likelihood class to be subclassed by other likelihoods

Parameters: parameters (dict) -- A dictionary of the parameter names and associated values

log_likelihood()[source]: log likelihood function that can be used with Bilby. return the scalar log likelihood value.
