So how can we interpret a nomogram once we have the data? Well going back to the love triangle example, say we have two actors (trying to be optimistic here) considering the role to play Anton, two actress (again, optimistic) for Jane, and finally, John Krasinski (haven’t quite given up on him, I’m WAY too optimistic now, I know) and another actor for the role of Randy. So then, after running the logistic regression, we can assignment points to each role based on those regression results. So we can assign 100 points to John Krasinski over that other actor, 30 points to Anton 1 over Anton 2, and 50 points to Jane 1 over Jane 2. So if our casting were to include John Krasinski, Anton 1, and Jane 1, we would have 100 + 30 + 50 = 180, or 180% chance to have that casting over any other combination. Or if we were to have John Krasinski, Anton 2, and Jane 1, we would have 100 + 0 + 50 = 150, or 150% chance to have that casting over any other combination. And how do we determine the points? Well, that’s a topic for another week. Until then, call me John, just sayin’ … if we meet in Chicago, I’ll treat you to some authentic Chicago deep-dish pizza …
And yes, it is real pizza! Jon Stewart doesn’t know what he’s talking about!
So we covered a lot of Anton and a lot of Randy lately (yeah, no, I’m not gonna even lie … that’s why I brought my trilogy straight up) but today I’m going to work through an example with the object of their affection, the love of their lives, the third side in their love triangle, the … well, hope you get the picture. And that person is Jane. Yes. Jane’s heart truly only belongs to one of them, to the one and only she is always devoted and to that one is … the one you find out about when you read the books! And how does she know if she’ll get to a dimension with that one and only? Well, she can look at a nomogram! Like this!
And what is that you may ask? Well, it’s basically a chart that can tell her the probability of her being with her one and only? And how does this chart tell her that? Well again, it depends on different parameters in the model that we got from logistic regression (like in Jane’s case, where does she live, what job does she have, and who is her one and only … again, you know what to do to find out). But wait … wait … wait … that’s not the most romantic model ever, you say? Well, maybe not but just think how romantic it can be once Jane is in the right dimension with her one true love!
Ah, that’s more like it! Until next time, you know where to find out who is Jane’s one true love 😉
