This dataset is obtained from a kaggle competition called Walmart Recruiting - Store Sales Forecasting which took place 8 years ago, from 20-Feb-2014 to 06-May-2014.

About - Dataset

This dataset consists of historical sales data for 45 Walmart stores located in different regions. Each store contains a number of departments, and we have to predict the department-wide weekly sales for each store.

In addition, Walmart runs several promotional markdown events throughout the year. These markdowns precede prominent holidays, the four largest of which are the Super Bowl, Labor Day, Thanksgiving, and Christmas. The weeks including these holidays are weighted five times higher in the evaluation than non-holiday weeks. Part of the challenge presented by this competition is modeling the effects of markdowns on these holiday weeks in the absence of complete/ideal historical data.
