Anscombe's Quartet

I love Anscombe's Quartet. Four obviously different sets of X-Y data (so, like, on the XY plane, a graph), but with exactly the same basic statistics (descriptives). Yes, you have to know your data and graph your data. (So, from the numbers they "look" the same, but when you graph them you see they are actually quite different.)


Portal and Skyrim!

I don't play on PC so I missed this from seven years (seven!) ago when it came out, but they put Wheatley the AI from Portal into Skyrim. I love it.

Zelda and Skyrim!

TL;DR: Three Zelda items in Skyrim on the Switch! (Official, not even a mod or anything.)

I love game cross-fertilization, and often it's official homage to some piece of sci-fi or fantasy in a game (lots of examples here in my blog, but really I only have a very small amount overall).

Recently I looked at the Easter Eggs page for Skyrim, which has Easter Eggs from a wonderfully wide selection of sources and lots of homage. More recently I was watching some Skyrim on the Nintendo Switch, and wondered if there was a use for the amiibos, and, indeed, there is!

What's super cool is that they give you a chance to get three Zelda items from the Switch's beautiful Zelda game (Breath of the Wild), the tunic, shield, and sword.

Here's the shield (with the tunic and sword) from an image on the wiki (linked to the wiki, not copied here, so maybe it will break one day), it's awesome!

Sorting Out Regressions

A great post over at R-Bloggers, [link broken as of 12/2020] "15 Types of Regression you should know." Also, how to choose which one is the right one? So many stats books (I have a few) are just terrible. They tend to throw stats language at people, and it's incredibly bizarre (p-hat? a hat? are you kidding me?) which is a problem because language is supposed to enlighten, not confuse. They also, at least for my English-language background, tend to throw Greek letters around and assume you know what the heck they are, which is an idiotic assumption. Again, language, especially in a textbook that is supposed to be explaining things, should be enlightening and clear, not obtuse. But, all the textbooks I have rarely cover anything but the most basic regression, and they always throw the regression equation at you, which is weird since never have I seen a paper with a regression equation in it, it's always a table.


Edit: Except now the post is no longer there and the URL redirects to R-Bloggers' best guess. Possibly this is the post, or something like it: https://www.listendata.com/2018/03/regression-analysis.html
