## Challenge #296: Breaking News - Headlines and Keywords

7 - Meteor

8 - Asteroid

All,

Spoiler
So, I started out with a Formula Tool with a DateTime Format to convert the Day to the weekday. I then used two daisy chained Find and Replace Tools to find "Football".

-The Predictive Part was fun as I used the ARIMA Model and then  TS Forecast Model.
-I used the summation tool and sum, versus average values. Reconstructing the months and years for the future periods was interesting after I used a RecordID starting with 13 as the start of the future periods. I used a Multi-Row Formula was ROW-12 in order to add future months and then years based on Record ID.

--Please let me know if anyone did this differently as I am really interested to see what the other options are as I know that there is a way to do the Year in Mult-row formula, but I am out of time for the week.
-Cheers!

Matt

Does it make sense to predict comments when those articles in Dec have just had less time to accumulate comments than those in Jan? I went with the RunTotal because of that.
