Interpolation and Extrapolation of Amounts based on dataset

[Misulici]

Hey guys,

I've found myself in a bit of a rabbit hole on the topic of Interpolating and Extrapolating amounts.

I have certain levels for which the amounts are missing, per each company, and I am trying to either interpolate or extrapolate the missing values based on the existing values and their growth/decay trends. Probably I am overcomplicating myself and thus I've ended up in a rabbit hole and ended up writing this post through which I am asking for your opinion on how would you perform an interpolation/extrapolation based on a decay/growth factor in Alteryx while making use of the attached sample file.

Any idea is welcomed!

Thanks in advance!

@Misulici 
I gave a try with simple linear one

Hey @Qiu ,

Thanks for this one!

Love the idea. I've just downloaded the flow and will explore the idea a bit more in depth to see where it takes me.

Will get back on the note, once I've managed to go through it myself.

Thanks again!

Hi @Qiu 

Thanks again for sharing your idea with me!

Much appreciated!

Sorry it took me a bit to get back to you! I've been digging into it and trying out a few different options, since it looks like there’s more than one way to approach it depending on what fits best.

Returning to your proposal I did notice an item on Company_1. It appears that that the Levels lower than 5 (the known value) grow in value, rather than decreasing. Any idea on how to avoid this? Maybe a reverse sorting to fit the lower Levels might be an idea. What do you think?

The same is occurring on Company_2, as well.

Thanks a lot!

Cheers,
