Abstract. Forecasting is a vital ingredient in the making of both long-term and short-term plans.

Statistical Methods for Forecasting is a comprehensive, readable treatment of statistical methods and models used to produce short-term forecasts. The interconnections between the forecasting models and methods are thoroughly explained, and the gap between theory and practice is successfully by: So far, many studies have been conducted on forecasting models for the building electric energy consumption based on ML techniques such as SVR, ANN, and tree-based methods [9,11].Table 1 summarizes the information about the selected papers, and these studies are described in detail subsequently.

Short-term forecasts are used in many management decisions, for example in harvest decisions, and often data are unable to develop mechanistic models. Time-series models may provide an alternative in such situations. Comparisons of time-series model forecasts to more traditional stock assessments forecasts are in progress.

Forecasting long term oil prices should be done by watching marginal costs, but with attention to political changes in access to resources and ignoring cyclical cost fluctuations.
Short-term passenger flow forecasting is an important data support for urban rail transit operation planning; it improves passenger flow organization, gives early-warning for oversaturation, and improves transportation service and safety.
Many forecast models have been proposed to.

Forecasting is the process of making predictions of the future based on past and present data and most commonly by analysis of trends.
A commonplace example might be estimation of some variable of interest at some specified future date. Prediction is a similar, but more general term. Both might refer to formal statistical methods employing time series, cross-sectional or longitudinal data, or.
The application experiment is based on AFC data of Confucius Temple station of Nanjing metro line three. Prediction time interval is set as 5 and 15 min. Comparison results show that accuracy of both models is higher in 15 min interval than in 5 min interval. NARNN has greater accuracy and adaptability than the ARMIA model.
short-term sales forecasting, two adaptive methods for seasonal sales forecasting have been developed.
The conclusions reached are that for most industrial purposes short-term sales forecasting methods should contain as few parameters as possible, that Brown's one-parameter method is to be recom-mended for non-seasonal forecasting and that the.

exploiting both volatility history and order book features for short-term volatility forecasting. By leveraging rolling and in-cremental learning and evaluation procedures, we demonstrate the prediction performance of our model as well as studying the robustness, in comparison to a variety of statistical and machine learning baselines.
I think short term forecasting is usually used in short term objectives covering less than one year for example material requirement planning, scheduling, budgeting e.t.c while long term forecasting is usually used to predict the the long term objectives covering more than five years for example product diversification, sales and advertisement.

series itself. Indeed, univariate models are often used for prediction up to about four to six hours ahead, and, due to the expense or unavailability of weather forecasts, univariate methods are sometimes used for longer lead times.
In a recent study , methods for short-term load forecasting are reviewed, and two intraday load time series are. The more distinct the methods or data sources used for the component forecasts are (the more they are independent from another) the higher is the expected improvement on forecasting accuracy compared to the best individual forecasts (Armstrong ).
