HI! I installed the MORETESTS package but it doesn't appears in the menu. How can I solve this problem? Thanks in advance any help.

Hey @ERMONTORO,
we can define the "moretests" module as an Add-on to add some tests to the base statistics.
Once installed, you won't find it in the ribbon, but the additional tests will be there where they can be used.
To give you an idea I am attaching a screenshot in which there is a simple one-way ANOVA, where on the left (moretests is not installed), for a homogeneity test request you have an output of only Levene's test. On the right (moretests installed), it is added to the Levene test and also that of Bartlett (with a note about it in the foot of the table).
Also for the request for a Normality test, with moretests installed, the Kolmogorov-Smirnov and Anderson-Darling tests are added to the basic Shapiro-Wilk.

If you try other basic analyzes, you will be able to check the contribution of moretests.

Thank you very much!!!

My doubts are, if the first step is check normality, why cant find normality test out of other test? Moreover I have different results for the same variable when analyze through t-test for one varible, and t-test for relations variables for normality test, how its possible?
