Understand The Problem Statement and Business Case
How to predict future daily sales? How will holidays affect the predict results?
To predict daily sales in the future, we will do a time series analysis task. Unlike the regression task that predicts a variable (dependent) with other variables (independent), time series analysis uses endogenous factors, namely factors derived from historical data that will be predicted itself. However, on this occasion we will add exogenous factors to help predict, for example, holidays.
