I have developed custom Standard Deviation based on different average like the:
1. Geometrical average
2. Harmonic average
3. Quadratic average
As shown in the attached pic, i would like to understand why, for the same Period:
1. The Regular Stdev is almost equal to the Harmonic StdDev
2. The Geom Stdev is almost equal to the Quadratic StdDev
It's more like a maths problem but i would be interested to have a feedback...
Thanks
