First, I describe and motivate the idea behind using data envelope analysis to conduct performance comparisons between units and complete a small version of it in a nonlinear model. Please watch this video - (~15min). You need not recreate what I do in the video as the Excel file I completed in the video is downloadable here: 09 VidLec PerformanceAssessment.xlsx e. However, you will want to follow along enough to be able to recreate the same analysis on a new dataset. After watching the video, please answer the following question: What is the interpretation of a store's efficiency score equal to 1, versus less than 1?
