[R] [EXTERNAL] Re: "chi-square" | "chi-squared" | "chi squared" | "chi square" ?

Interesting!

Both UK and US show quite a bit more "square" than "squared" in your
sample, with maybe an even stronger tendency for "square" in US than in UK.

I like "squared" better because it fits better with standard English
pronunciation of, say, \sigma^2 or x^2 or r^2.
