Id like to see if a combination of those 5 measurements is able to distinguish a given word (e. e. x∼N(μ,Σ). It is easy to require tests that are quite complex, testing all possible combinations of variables, but this may not be necessary for your objectives.
The conditional expectation of X1 given that X2 is smaller/bigger than z is:22367
where the final ratio here is called the inverse Mills ratio.

1. There are seven independent variables that are labels (7 vowel spoken by subjects). We are simply seeking to establish if there is variation and how much is the variation. But if a random vector has a multivariate normal distribution then any two or more of its components that are uncorrelated are independent. MatthewHello Matthew,
Hotellings T-Square test does require normality, although these sorts of tests are pretty robust to violations of normality.

474 9. The result of the DATA step will be a SAS data set named “mahal” that will include the original variables, the standardized principal component scores (named prin1-prin4) and the Mahalanobis distance (named dist2). Some says i need to use discriminate function analysis to analyze it completely.
