Hi guys, I wrote the wrong answer for the smoothing constant of a=0, 2. The workings are correct, I made a mistake on my calculator. The method stays the same. I changed the tumblin and inserted the right answers. They are written in pen on the table. ❤

When calculating the error term, i do not understand why you are subtracting the previous predicted term.... ain't we trying to find the difference between the predicted term the observed term of the same time ?
