, remove_data=False)[source]

save a pickle of this instance


fname : string or filehandle

fname can be a string to a file path or filename, or a filehandle.

remove_data : bool

If False (default), then the instance is pickled without changes. If True, then all arrays with length nobs are set to None before pickling. See the remove_data method. In some cases not all arrays will be set to None.


If remove_data is true and the model result does not implement a remove_data method then this will raise an exception.
