T-stat for multiple regression game, referring, multiple, specific, example

badonkus

A little late in the game to be asking this, but I assumed I had the basics of quant (at least compared to some sections of PM/Econ)...

Anyway, Stalls indicates the formula to solve for t-stat of regression coefficient is:

Tcalc = b1-B1/sb1

CFAi indicates the formula is simply b1/sb1

If you need a specific example I am referring to #40 of the CFAi PM mocks.
