10.04.2016 · It seems that add_constant () doesn't works if there is already a column with variance=0, i.e. a column with all identical values. It is the case in my dataset (not mentioned in the example above (54 columns)). The solution is to add has_constant option in the add_constant () function, like this: sm.add_constant (testmat [60], has_constant='add')
