Subject: [R] Testing for normality of residuals in a regression model
Hi all,
Is it possible to have a test value for assessing the normality of residuals from a linear regression model, instead of simply relying on qqplots?
I've tried to use fitdistr to try and fit the residuals with a normal distribution, but fitdsitr only returns the parameters of the distribution and the standard errors, not the p-value. Am I missing something?
Cheers,
Federico
