satlas.stats.fitting.likelihood_x_err

satlas.stats.fitting.likelihood_x_err(f, x, y, xerr, func)

Calculates the loglikelihood for a model given x and y values. Incorporates a common given error on the x-axis.

Parameters:

• f (BaseModel) – Model object set to current parameters.
• x (array_like) – Experimental data for the x-axis.
• y (array_like) – Experimental data for the y-axis.
• xerr (float) – Experimental uncertainty on x.
• func (function) – Function taking (y_data, y_model) as input, and returning the loglikelihood that the data is drawn from a distribution characterized by the model.

Returns:

Return type:

array_like
