Do you have any experience working with statistical models? If so, please describe in as much detail as possible the statistical model you worked on and your role in creating it or using it to answer a business question.

"As a data analyst, I have had experience working with statisticians to help them build their models. Although I do not have direct experience building the model, I have aided them by analyzing data and ensuring they have access to the appropriate data. The model was built to help the sales team identify customers most likely to purchase additional products and services and when they would be most apt to make that decision. This model increased the sales team's efficiency so we didn't waste time with customers who were unlikely to purchase again in the near future. I aided in identifying the appropriate variables used in the model and evaluating the efficacy of the model upon completion."
