The canonical discriminant function coefficients are also called
unstandardized loadings because they apply to the unstandardized discriminating variables (x and y).
Because we have only two groups, there is only one discriminant function. From the coefficients or
loadings of this discriminant function, we obtain a one-dimensional projection of the data that gives
maximal separation between the two groups relative to the spread within the groups. The estat
loadings postestimation command displayed these loadings;
