It is rather straight forward to do a linear regression, but i ckecked lots of options but coul not find the r, deriving it from R(square) is a bit tedious. Is there a way to include the regession equation, in the graph as with Excel. Is it possible to print the confidence interval for a correlation coefficient -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu]On Behalf Of Martin Weiss Sent: Freitag, 8.

Non-rejection of the null does not imply that the data are normally distributed; it does mean that you do not find convincing evidence against the assertion that they derive from a normal distribution. Note that the 95% confidence level that you are implying in your post means that you will falsely reject the null in 5% of your tests. The information that tests such as -swilk- provide is less than most users imagine... -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Carlo Georges Sent: Friday, August 08, 2008 9:35 AM To: statalist@hsphsun2.harvard.edu Subject: st: swilk test Ho: In using the shapiro wilk test for testing normality, is it correct that the H0 (NULL hypothsis) is :H0 data are normally distributed, so when p< 0,05 we reject Ho and data are not normally distributed.
