## Nothing marginal about pairwise correlations!

So now we know how to map values from one matrix to another, we might want to see mapping one column could effect mapping another column.  The problem is that sometimes we don’t know how the columns interact with each other though.  In other words, we don’t know their joint distribution.  We might have a hunch about the joint distribution if we look at the pairwise correlation between two variables. So, say Randy wants to get the 411 on which dimension he is in based on where Tina is employed — if she is employed in that realm.  So say he looks at the Houston and Indianapolis realms and sees that she’s employed at a computer store or a printer store.  And since she works at those stores in justified dimensions, he can further deduce that it is a good dimension and Tina is in fact employed by good Anton.  Or is he … meaning Anton being good or … well, you know how to find out by now!  And yeah, Tina might have a more exciting life in the unjustified dimension … but does she have access to a nearby Chipotle there?  Or a Barnes & Noble where she could order a copy of the Order of The Dimensions series?  Or an AMC theater showing the Order of the Dimensions movie or … yeah, I’ll stop.  But anyway, the point is working at a computer or printer store at a shopping center has its benefits. Like she’s most likely near a CVS or Walgreens where they may also carry DVDs of … well, you get the picture.  But still, you can always check out the Order of The Dimensions series at Barnes & Nobel until next time!

## I see the ICC

And today we’ll talk about the ICC, or intraclass correlation coefficient, which basically tells us whether most of the variation takes place between subjects or within subjects. Like say we have different realms (no, I did not say dimensions — I said realms!) and we want to see if the differences between justified dimensions, I mean, realms or if the differences between them are greater.  So if the five main characters within them are similar and, say, have similar lifestyles, the ICC will probably be higher.  But — and now comes my version of the exciting part — if bad Anton got switched with good Anton in some of those dimen … realms, there could be more variation within them than between them so the ICC could drop.  And how do we know if bad Anton switched himself with his good alter?  Well, that could be tricky.  Even trickier than finding the cat in this photo.

What?  You did?  That fast?  Well, good for you! Until next time … when I’ll pull one over you yet.  Can’t believe it took you that fast as it took me … never mind.
