So how do we know the probability that we’re in a good dimension given a bunch of other factors? Well, we can for example check Tina’s marital status, employment status, the climate of the place where she lives, etc. and multiple them by these things called regression coefficients (something we’ll cover yet another time) and add them up together to get a number say, y. Then we take the exponential of y, to get, say, exp(y). Something cool to wiki. And then our probability is exp(y)/[1+exp(y)]. Voila!! So again, how the heck do we get y?? Ah … like I said, we’ll cover that next time! Until then, have a good week — oh, and if you still need something for dad this Father’s Day.
