cwitools.modeling.rss_func1d

cwitools.modeling.rss_func1d(model_params, model_func, x, y, y_var, *args)

Calculate the residual sum of squares for a 1D model + 1D data.

Parameters:

• model_params (list) – The parameters of the model
• model_func (callable) – The model function, of form f(params, x)
• x (numpy.array) – The observed x-axis positions
• y (numpy.array) – The observed y-axis values to fit to
• y_var (numpy.array) – Variance on y input. Required positional argument, but you may simply provide a value of 1 to ignore.

Returns:

The residual sum of squares

Return type:

float
