     theta : ndarray, list, vector
-        Theta consists of 2+2b values. If ``X=None`` then 4 values should be provided.
+        Theta consists of 4 values.
     y : ndarray, list, vector
         1-dimensional vector of n observed values. These are the gold-standard :math:`Y` measurements in the external
