Fishery Landing Forecasting Using Wavelet-Based Autoregressive Integrated Moving Average Models

الملخص EN

The accuracy of the wavelet-ARIMA (WA) model in monthly fishery landing forecasting is investigated in the study.

In the first part of the study, the discrete wallet transform (DWT) is used to decompose fishery landing time series data.

Then ARIMA, as a powerful forecasting tool, is implemented to predict each wavelet transform subseries components independently.

Finally, the prediction results of the modeled subseries components are summed to formulate an ensemble forecast for the original fishery landing series.

To assess the effectiveness of this model, monthly fishery landing recorded data from East Johor and Pahang states of Peninsular Malaysia have been used as a case study.

The result of the study shows that the proposed model was found to provide more accurate fishery landing series forecasts than the individual ARIMA model.
