Multiple t test in MATLAB

I have a set of data for three kinds of patients who :

1- have the disease

2- might be at risk to have the disease

3- healthy people who dont

I need to compare x,y, and z coordinates of their MRIs.

What kind of T test should I be using as I'm very confused about it?

It might help if you post the data.

Hi,

Please refer to the documentation and examples related to multcompare for multiple comparison tests.

I need to compare the x variables of all of the above mentioned patients. for that what I should I be using?

[Prachi Kulkarni]

Hi,

If the x-coordinates are in the vector x and the category of the disease categories are in the vector d, you can perform the test as follows.

[p,t,stats] = anova1(d,x);
c = multcompare(stats);
