statsmodels.tools.tools. add_constant (data, prepend = True, has_constant = 'skip') [source] ¶ Add a column of ones to an array. Parameters data array_like. A column-ordered design matrix. prepend bool. If true, the constant is in the first column. Else the constant is appended (last column). has_constant str {‘raise’, ‘add’, ‘skip’} Behavior if data already has a constant. The default will return data without adding another constant.

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')
