Calculate Rolling **Beta.distr** in column ~K and rolling ~Gamma.dist.

Hi David,
The Beta actually represents the trend ,and in the analyses,a comparison to the former value.
The Gamma shows the seasonal patterns,bot the values are held against the Alpha value,which is the baseline.
I follow the Multiplicative triple model .
This is why is i tried to put the Beta and Gamma in there :slight_smile:

Hope the above helps.
Cheers
Ron
