Prediction of global sea cucumber capture production based on the exponential smoothing and ARIMA models
Sea cucumber catch has followed “boom-and-bust” patterns over the period of 60 years from 1950-2010, and sea cucumber fisheries have had important ecological, economic and societal roles. However, sea cucumber fisheries have not been explored systematically, especially in terms of catch change trends. Sea cucumbers are relatively sedentary species. An attempt was made to explore whether the tim...

متن کاملForecasting based on state space models for exponential smoothing
In business, there is a frequent need for fully automatic forecasting that takes into account trend, seasonality and other features of the data without need for human intervention. In supply chain management, for example, forecasts of demand are required on a regular basis for very large numbers of time series, so that inventory levels can be planned to provide an acceptable level of service to...
متن کاملSmooth Transition Exponential Smoothing
Adaptive exponential smoothing methods allow a smoothing parameter to change over time, in order to adapt to changes in the characteristics of the time series. However, these methods have tended to produce unstable forecasts and have performed poorly in empirical studies. This paper presents a new adaptive method, which enables a smoothing parameter to be modelled as a logistic function of a us...
متن کاملExponential Smoothing Mod
Applications of exponential smoothing to forecast time series usually rely on three basic methods: simple exponential smoothing, trend corrected exponential smoothing and a seasonal variation thereof. A common approach to select the method appropriate to a particular time series is based on prediction validation on a withheld part of the sample using criteria such as the mean absolute percentag...
