I have applied 3 methods say Method-1, Method-2 and Method-3 to a dataset.
I applied modified versions of these methods say Method-1M, Method-2M and Method-3M.
while I can calculate the error between
-Method-1 and Method-1M
- Method-2 and Method-2M
- Method-3 and Method-3M
to see if the modified versions are better or not, I can also have other several combinations for error check.
My question is, is there any statistical method (say ANOVA) that can tell me in a single go that a method is better in terms of low error as compared to existing methods as well as among the modified versions?
