I'm sure there is a way to do this either in Fit Model, Time Series Analysis, or Time Series Forecast. I have two time series grouped by age bracket. Columns are population and health care expenditure. I can do some forecast modeling no problem with the data individually. But, I have a population boom in the 40-60 year age bracket, so when they become the 70-80 year age bracket, they will cause an increase in the burden of health care which won't be captured if I just do the forecast on the expenditure column itself.
Thanks for any advice and happy new year to everyone out there!
Best,
Greg
