Predicting Monthly Car Sales for Brands in US: First Step

August 6, 2014

(This article was first published on sweissblaug, and kindly contributed to R-bloggers)

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 ( 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!
