ttest2 negative value
显示 更早的评论
Hi all,
having two vectors x and y, I would like to test which one has the smallest mean with ttest2. I saw in an paper describing rapidly the ttest2 function that it could return either 1 (if mean(x) > meay(y)) or 0 (if mean(x)==mean(y)) or -1 (if mean(x)<mean(y)). However, in the official documentation, there is no negative which can be returned .
Are the information I got false ? How can obtained the described return results ? (1 or 0 or -1).
Many thanks

It would help to know what MATLAB version (release) you are using. I am not aware that option ever existed.
If you want to specifically test that the first mean is different from, greater than, or less than the second mean, use the 'Tail' (link) name-value pair argument.
