Module 3 Project: Time Series Forecasting & PredictionThis assignment is designed to give you hands-on experience in performing both regression and time series forecasting. You will be given a particular real-life time series, and are asked to perform regression for predictions and to perform a time series forecasting. In addition, you are asked to perform a sensitivity analysis by using different parameter values and calculating measures of error for each of those values. Use Excel all statistical work.
