My idea was that the limits are
and that the anti-derivative of dy was
xlog(1+y^2)
but that seems wrong...
maybe use these limits instead
and start with dx?
gives us
then we take dy
guess, i figured it out eventually with the help of wolfram with the last integration
I want to do multiple linear regression, but one of the requirements is the residuals to be normally distributed, and I can check that with QQplots but then the QQ plot shows it is about 95% of data fit into the normal line, but 5% is way off!
can I still proceed ?*or do I have to find a way...
