satlas.stats.fitting.likelihood_loglikelihood(f, x, y, xerr, func)[source]¶

Given a parameters object, a Model object, experimental data and a loglikelihood function, calculates the loglikelihood for all data points.

Parameters:	f (`BaseModel`) – Model object containing all the information about the fit; will be fitted to the given data. x (array_like) – Experimental data for the x-axis. y (array_like) – Experimental data for the y-axis. xerr (array_like) – Experimental data on x. func (function) – Function calculating the loglikelihood of y_data being drawn from a distribution characterized by y_model.
Returns:	Array containing the loglikelihood for each seperate datapoint.
Return type:	array_like
