REGRESS Question [message #36730]

I am having difficulty working with the REGRESS function. I
continually get values <1 for my slope when doing a regression between
two vectors. When I do a regression mapping y to x (slope =
regress(x, y, const = const)) and when I do a regression mapping x to
y (slope = regress(y, x, const = const) I get a slope<1 for both
calculations. Shouldn't the y=mx+b of these two regressions be
inverses of each other (leading to one slope>1, and one<1?) Maybe I
am misunderstanding regressions?
Thanks,
kevin
