How to perform statistical test with multiple variables
Hi neha, Ouch! I've just been run over by homework. What you are probably being asked to do is an "omnibus test", but I can't figure out what you are actually testing. Maybe that phrase will help you in _your_ search for the answer. Jim

Hello everyone,
I have 'mean absolute error' values from different folds of CV of 6 ML
models..
a= c(0.3, 0.5, ..... 0.4)
b= c(0.4, 0.6,...... 0.2)
....
..
f= c(0.1, 0.4, .....0.5)
Now algorithm 'a' performed better than all the others (in terms of mean
absolute error scores) and then I used wilcoxon signed rank test to compare
'a' with all other models for significance difference.
Now, I have been asked to compare all the models with all others for
significant differences at once and not compare one with the other, how can
I do it, plz guide me? At this time, I just know about the Wilcoxon signed
rank test.
