IntroductionForecasting is a process of predicting or estimating the future based on past and present data. Forecasting provides information about the potential future events and their consequences for the organisation. It may not reduce the complications and uncertainty of the future. However, it increases the confidence of the management to make important decisions. Forecasting is the basis of premising. Forecasting uses many statistical techniques. Therefore, it is also called as Statistical Analysis.Forecasting vs. Prediction:Forecasting: Estimating future by casting forward from past data.Prediction: Estimating future based on any subjective consideration other than just past data.

Holt’s Method We begin with an estimate of the intercept and slope at the

start (by Lin. Reg.?) lt = α*Yt + (1-α)*(lt-1 + bt-1) bt = β*(lt – lt-1) + (1- β)*bt-1 Yt is obs. demand; lt estimate of the label of the series at time t; Bt estimate od the scope of the series at time t; Ft+m = lt+ bt*m (forecast for time m into the future)
