Body Styles

Results

Research Question: How frequent are different vehicle body styles in the target population?

As shown in Figure 1, it appars that “SPORT UTILITY 4-DR” and “SEDAN 4-DR” are the clear winners in the sample. Based on prior experience, the author believes that these body styles are also most frequent in the target population.

Figure 1: Solid dots represent observed proportions in the sample. Error bars go out +/-1 simulated mean absolute error for each body style.

Appendix: Sensitivity Analysis

Figure 2: Non-response Simulation. The estimate in orange (shown for comparison only) is the result of multiplying the observed proportions by N - n, where N is assumed to be 500000.
