Forecast Strategy 14 (Weighted Moving Average)

[Former Member]

Hi!

I have some doubts about Strategy 14. The user has created a profile with this strategy and has done some forecast with this profile but the forecast KF is still empty.

So, i check her profile and i discover that when i key 14 in the forecast strategy field a popup appears : "Specify a weighting group for forecast strategy 14".

Of course the user didn't specify a weighting group but she has been able to save the profile.

Is this weighting group obligatory for strategy 14?

I try to create one but i don't understand the meaning of the fields required to create such a group.

What is the windows witch appears when i click on the <i>Edit time series</i> button?

Thanks by advance,

LB

Hi Laurent,

Yes, you have to specify a weighting group for forecast strategy 14. This is a copy of the system help:If you are using forecast strategy 14 (weighted moving average), choose or create a weighting profile using F4 Help. Otherwise, leave this field blank

When you click on the Edit time series button a screen with as many periods as you specify for your time series appears.

Here you can specify percentage factors, in order to do more weight to some historical values.

Here is a link that could help you:

I hope this can help you.

Hi!

I have another doubt.

I write for the first month of history 110% and for others months I let the fields empty. An empty field is equals to 0% or to 100%?

Thanks by advance,
