With no further constraints, the parameters a and v_i do not have a unique solution. You can see that by rearranging the terms in equation (1): WebJul 27, 2024 · Because your adjusted R2 is essentially zero, it suggests that the result of your formula has been to take the mean of the response variable Y. So I would expect that your effect estimate X=0.339422, is essentially the mean of Y. This answers your first question -- actually the intercept is not missing. The X=0.339422 is an intercept.
