<t>Papercut, Thanks for responding. So, if my parameter estimates give me the model dr =.0118(.05124-rt)dt + .0003 dWt, when fitted to daily data, would my annualized model be dr = 2.97(.05124-rt)dt + .00476 dWt, where 2.97 = .0118 * 252 and .00476 = .0003 * sqrt(252)?Let me know if you have a chanc...
