Web9 de out. de 2016 · When using larger lag lenghts(9 through 12), the autocorrelation problem disappears, even though non-normality and heterokedasticity remains. Web2. Does the non-normality matter in using regression for prediction? Hi all, In the Q-Q plot of the residuals after linear regression, the residuals turned out to be highly non-Gaussian. Most of the points (95%) are below a 45º straight line. And those below the straight line are all on the lower side. The shape of the curve looks like f ( x ...
