Hi Bart,

So you have a list of the first 25 songs, and you try to build a model that will have the same results based on weekly data?
what is the goal if you already have the yearly list?

I assume that the yearly list and the weekly data won't have a full match...

Not sure what are the data and source of data? B3=53, is this sale? what is the rank BN?
Maybe you look at sales and compare to end of year votes? In this case, you will never have full "agreement" between the model and the rank

Hi Bart,

Yearly rank is done once a year and depend on people mind at the end of the year.
I assume that like doing a regression,(in a regression model the estimate Y and Y are not always equal) , your model will not predict exactly the yearly rank. And if you find model that will predict the numbers it would be probably over fit and won't predict other data.
