'FactorResults' Object Has No Attribute 'endog' - Python Error Solution

This error message occurs when you attempt to access the attribute 'endog' on an object of class 'FactorResults', but this attribute does not exist in this class.

It's possible that you are using the wrong method or attribute to access the data you need. You should check the documentation for 'FactorResults' to see what attributes and methods are available and how to access the data you require.

Alternatively, the object you are using might not be an actual instance of 'FactorResults' and is something else entirely. In this case, examine your code to see where the object is being created and ensure that it is indeed an instance of 'FactorResults'.
