How to define the periodicity_Hint value

Hi, all experts here,

I am having a question on defining the value of Periodicity_hint. e.g, I wanna predict the monthly sales amont of a product, and assume the data follows monthly patterns, then in this case, what value should we set for the periodicity_hint parametre?

Thanks a lot for your kind attention and I am looking forward to hearing from you shortly.

With best regards,

Yours sincerely,

The preiodicity hint should be specified as a string that looks as follows:

{a,b,c}

where a,b and c are the hints you specify. In your example, if you have a periodicity in the data of 12, the hint string would look like {12}.

But my another question on it is: assume we did not know the periodicity of the data, so it is always better to leave this propertity blank in which case the system willl automatically detect the periodicity of the data?

Thank you very much and I am looking forward to hearing from you shortly for your further advices.

|||Exactly: the system tries to detect the periodicity of the data.
If you leave this blank, the results of the detection are used.

You should provide a value for this parameter when:
- you know the periodicity (and want to hint the system, before it runs the detection step) OR
- you know the periodicity and want to correct the algorithm's auto-detection results

In both cases, your periodicity hints will be analyzed together with the periods automatically detected by the algorithm|||

Hi, all friends,

Thanks a lot for your kind advices.
