Mauchly's test of sphericity

[Frederick Asare]

I need help please.

After running a one way repeated measure ANOVA for my data, I got a result which identified the repeated variable correctly. I wanted to further conduct mauchly test of sphericity so I installed it with the command "ssc install mauchly" which was successfully installed.

However, when I tried to run the mauchly test with this command "mauchly dependent variable, m(repeat variable)", (NB: the repeat variable is the one which was identified during the anova test), it gives this result "<istmt>: 3499 mm_repeat() not found".
How do I fix it please?

The author of the community-contributed mauchly command neglected to document the requirement that the community-contributed moremata package - which contains the mm_repeat() Mata function - is required under some circumstances by mauchly and should be installed.

ssc install moremata
