4.7.12. statsmodels.tools.sm_exceptions¶
Contains custom errors and warnings.
Errors should derive from Exception or another custom error. Custom errors are only needed it standard errors, for example ValueError or TypeError, are not accurate descriptions of the reason for the error.
Warnings should derive from either an existing warning or another custom warning, and should usually be accompanied by a sting using the format warning_name_doc that services as a generic message to use when the warning is raised.
