So what is keeping me from knitting as much as I'd like to: this, the CAIA exam which I have in 19 days! Yikes! It is chalk full of formulas, statistics, and terms like leptokurtosis and heteroskedasticity. I used to know this stuff stone cold, believe it or not I have an MBA from University of Chicago with concentrations in Finance and Statistics; but that was many years ago & let's just say that my last 6 years as a SAHM have not exactly improved my statistical skills. Plus, my retention is not what it was 20 years ago!
