Hi everyone,

I'm running a multiple linear regression with 170 cases. To check for normality of residuals, I use the following commands.

Code:
predict x, resid
histogram x, kdensity normal
qnorm x
pnorm x

Which yield the following plots. Can this still be considered as acceptable (qnorm and pnorm looks ok to me, while histogram shows skewness)?

If not, can I perform any internal robustness checks like transforming the DV to see if the results from this regression are "valid"?
