Re: Hypothesis testing, two different rates

OOOPS ..missed a decimal pointer on the coefficients

Furthermore the "relationship" is not only significant
contemporaneously ( coeff = -57) BUT there is also a significant
lagged relationship suggesting the the prior year's OD rate can
significantly help the prediction of the current years ARREST RATE (
coeff = +51 )


Simplifying yields that ARREST RATE = 50 * first differences in OD RATE
