I’ve set out to produce monthly forecasts of monthly car sales by brand in the US. So far I’ve made a SUTSE dynamic linear model (code on Github) and created a Shiny app (http://sweiss.shinyapps.io/carvis/) as a prototype (no predictions yet).
Basically, I want to combine my interest in cars with my interest in stats.
My current roadblock is the how slow the code runs, but I intend to have a speedy implementation using RStan by next month.
If anyone has tips or suggestions, please comment!
