Forecasting is the method of estimation of the future by taking into account the past and present data.It helps in the determination of direction of future trends. Forecasting helps in planning of business actions and create budget to cover the uncertainties as much as possible. Tableau uses exponential smoothing method for forecasting purpose. Exponential Smoothing is a method of time series forecasting for uni-variate data which can be extrapolated to understand the seasonal component and trend. It assigns exponentially weights for new to old observations, i.e.,   more weights are assigned to newer data than the older ones as newer data are considered to be more relevant.
