06.06.2020 · There is an inconsistency that occurs between Calling OLS (y, x).fit () on a single line and then generating the OLSResults object, and Calling lm=OLS (y, x) on one line, and then lm.fit () on a second line and then generating the OLSResults object. Case (2) results in an error when applying methods of the OLSResults object, but case (1) does not.
I've been attempting to fit this data by a Linear Regression, following a tutorial on bigdataexaminer. Everything was working fine up until this point.
