Hi all, I´m getting this warning with predict form lm.fit model, but the prediction still works.
I have read some old messages, and Prof. Ripley said that the matrix is collinear. Interestingly, when i make a regression like lag2 ~ lag1 + lag0 i do not get this message. Only with higher dimensions, like lag3 ~ lag2 + lag1 + lag0. It´s difficult to me to debug, because the regression is done with 45 or more points. Any suggestion? I used SVD matrix to reduce the space dimensionality and it works fine, but i want to make lm and rlm work too. Thanks for your attention.
