## Data Overview

The OJ dataset contains weekly sales data for different brands of orange juice at different Dominick's Finer Foods grocery store locations. 
This dataset originated as part of a larger collaboration between the University of Chicago Booth School of Business and Dominick's, which
led to the accumulation of data on prices and volumes across a large number of different products. The dataset has been augmented with local
demographic data that describes people living near each store. The version of the dataset we are using today focuses on orange juice sales 
across three different brands. You can read about the original dataset here: [Chicago Booth Dominick's Data](https://www.chicagobooth.edu/research/kilts/research-data/dominicks). The 'EconML' package hosts the orange juice specific version of this dataset here: [oj_large.csv]("https://raw.githubusercontent.com/py-why/EconML/refs/heads/data/datasets/OrangeJuice/oj_large.csv"). It contains over 29,000 rows and 17 
columns, with no missing data.
