In the study of performance...

One approach to standardizing sales data across different regions of the country may be to adjust for the relative wealth/purchasing power of the clientele in a given region. For example selling 50k USD merch in Lubbock, TX is more impressive performance than selling 50k USD merch in Beverly Hills, CA. Although it is possible to use the cases in your sample to build your region-standardized variables, these sample-based estimates can be incredibly biased and in fact could penalize truly high-performing regions.

Does anyone know of a resource? data table? method? that could provide estimates of how dollars equate across major regions of the country... Maybe by zipcode? Maybe this is related to cost of living or median income of region? any ideas?

The more valid, transparent and defensible the estimates (e.g., govt resource), the better. -Thanks!

  • $\begingroup$ i was wondering that too, but the economists won't be dealing with individual human performance. I can try over there :( This really is a question that a professional IO would be running into in their job while modeling human performance. $\endgroup$ – GoldenPandas Apr 3 '15 at 14:59
  • $\begingroup$ I think what makes it off-topic here is that there is no aspect of the question that deals with cognition or psychological processes in general. The crux of the question is more about an analysis technique and data sources. $\endgroup$ – Josh de Leeuw Apr 3 '15 at 19:43
