Hello,
I collected measurements of 15 separate animals at 5 time points (T1-T5). I would like to test for significant variation among individuals at each time point, but also across time points for each animal using a MANOVA with repeated measures. While formatting the data and running the code was quite straightforward, I'm struggling to find a good explanation of the output tables and how to interpret them.
Many thanks for the help.
Here is my code and the subsequent output tables I speak of:
rm = fitrm(my_table, 'T1-T5~animal');
manova(rm)
ans =
8×9 table
Within Between Statistic Value F RSquare df1 df2 pValue
