untill now i couldn't understand why in many disciplines of science there are specific terms and conventions. recently i have this problem in econometrics. for a typical person the expression "can accept" will exactly be having the same meaning with "cannot reject". at least for me it is. i don't know why in my book keeps sayying:
"if you cannot reject the null hypothesis of parameter instability..."
instead of
"if you can accept parameter null"
but now i see.
just to find evidence to reject an hypothesis is not a proof for accepting an alternative. sometimes you have evidence to reject everything
not like doing someting is not an evidence to like not to do it:)))
