For each vehicle in this dataset, there is a variable "INFERREDDATE" which is described as "Inferred Purchase Date Code". According to the data dictionary, the code is something like "A - 0-6 months, B - 7-12 months, etc.". So it is a relative date (how long ago it was purchased, maybe?). Does anyone know how to figure out a reference date? Like how many months ago it was purchased relative to the date the consumer was surveyed? I cannot find a survey date or any other date in this data or the corresponding Consumer Profiles data. To perform my analysis, I need to know at least in which calendar year a vehicle was purchased. Thanks for any advice!
