I think the Hedge Ratio should be params[1] and not as mentioned params[0] as it is the intercept.
Please correct me if I am wrong
Hi Jad
If you experiment with the code in the notebook in Section 7, Unit 11, you will see that the output of modelA.params is a pandas Series. Doing modelA.params[0] will return the value of this series, which in this case is treated as the hedge ratio. Hence, it should be 0 and not 1.
Had there been a constant (intercept) in the equation, in that situation modelA.params[1] would have fetched the hedge ratio and modelA.params[0] would have fetched the intercept.
Hope this helps.
