Context The idea is to predict the shopping time given a shopper id, store id, and the day the shopping was done. Content The training data contains by trip id the stores visited, the shopper id, the shopping start and end time. Acknowledgements I would like to acknowledge the data science team of Instacart for sending this out to me as a part of their recruitment process. Inspiration From the data is it possible to perform a multivariate time series analysis to predict shopping time? How to go about analysis on such data? I have added a preliminary analysis.
