Hi everyone,
You will see in the attached file, a set of command I used with the aim to check for normality of the data. However, I don't know how to interpret the graph obtained. Can you help me please?
Happy new year !
Thanking you in advance.
Have you tried running it through proc npar1way with normality tests?
Take a look at: SAS/QC(R) 9.3 User's Guide
Or check proc univariate normal ;
Graphic shows that long tails at both ends of the data distribution .Which means it is a skewed distribution, such as the lognormal is more appropriate than the normal distribution.
