Alpha Beta Parameter use

Hi All,

I am using Seasonal Model for my Univariate Profile.

I need some information on what is the Alpha, Gamma Parameter and Period Parameter use? What is the value should I maintained?

What is the Period definition?

Could anyone give information on the Alpha Gamma and Period Parameter use and how value range need maintained.

Mainly I need to know the use of Period Parameter.

Thanks,

Best Regards,
