Follwoing table shows the exponential smoothing forecast for 0.2:
Week Index alpha=0.2
1 7.35 #N/A
2 7.4 7.35
3 7.55 7.36
4 7.56 7.40
5 7.6 7.43
6 7.52 7.46
7 7.52 7.48
8 7.7 7.48
9 7.62 7.53
10 7.55 7.55
And following is the time series plot shows the same:
------------------------
Follwoing table is exponential smoothing for alpha=0.3
Week Index alpha=0.3
1 7.35 #N/A
2 7.4 7.35
3 7.55 7.37
4 7.56 7.42...
