You will use regress when you want to find out how Z behaves with respect to X and Y. The reason the second data set is not returning -1 for the slope is because you are forcing it to have an intercept at zero. If you include an intercept term, you get the expected -1 slope with a y-intercept of +6: x = [1:5]'. y = [5 4 3 2 1]'. b = regress (y, [x ones (size (x))]) b =. -1. Description. example.
