Hey guys,

I did a linear regression analysis and checked for the normality assumption. The plot (qnorm) and all the other graphs for normality look reasonable but the Swilk-test rejects the normality assumption and I dont't really understand why. Is it because of the sample size or is the model missspecified?

Swilk-test:

Variable | Obs W V z Prob>z
-------------+------------------------------------------------------
red | 707 0.97999 9.207 5.418 0.00000

Thanks in advance

Ben
