Sales promotions are a vehicle by which businesses increase the demand for and visibility of their products and/or services. Quantitative Forecasting Methods n These methods are used when historical data are available. Prototype these models by using high-level modeling languages such as MATLAB or R, or in software languages such as Python. However, econometric models usually fail to outperform simple time series extrapolative models. Typically, a forecasting model based on regression analysis specifies passenger origination (the dependent variable) as a function of one or more independent variables representing the regional economy such as employment, income, or gross domestic product (GDP), a price variable such as average fare level or yield (airline revenue per passenger mile), and sometimes an air service variable. The major statistical models are: Trend projection; Barometric; Econometric Each model is a better fit for some demand patterns than others. These exogenous factors together with fundamental supply and demand data result in the price solution for commodity prices.
