Noun form of "analytic"

I've been tasked with creating some custom website tracking for a CMS, similar to Google Analytics. I was going to title this area on the back-end as Analytics but I got a spell-check red squiggle and that sent me to a Google search which resulted in me finding out analytics isn't a real word.

So is there a noun form of analytic or am I just being stupid?

It absolutely is a word.

From Merriam-Webster:

an·a·lyt·ics
noun pl but singular or pl in constr \ˌa-nə-ˈli-tiks\
: the method of logical analysis
First Known Use of ANALYTICS
circa 1590

Traditionally, the noun form is analysis. The -sis ending in Greek is a noun form that gets changed into -ikos when it is made into an adjective, from which we get out -ic ending for lots of our adjectives. The word analytics was perhaps coined a very long time ago, but it has only recently been gaining currency, I think.
