Operational seasonal forecasting of crop performance.
Integrated, interdisciplinary crop performance forecasting systems, linked with appropriate decision and discussion support tools, could substantially improve operational decision making in agricultural management. Recent developments in connecting numerical weather prediction models and general circulation models with quantitative crop growth models offer the potential for development of integ...
متن کاملAssessing the Performance of MODIS NDVI and EVI for Seasonal Crop Yield Forecasting at the Ecodistrict Scale
Crop yield forecasting plays a vital role in coping with the challenges of the impacts of climate change on agriculture. Improvements in the timeliness and accuracy of yield forecasting by incorporating near real-time remote sensing data and the use of sophisticated statistical methods can improve our capacity to respond effectively to these challenges. The objectives of this study were (i) to ...
متن کاملForecasting performance of seasonal- dummy models relative to some alternatives
Abeysinghe (Economic Letters, 1991, 36, 175-197; Journal of Econometrics, 1994, forthcoming) showed that seasonal dummies in regressions may lead to spurious inference. This paper evaluates the post-sample forecasting performance of a seasonal-dummy ARIMA model with four other models. The results, in general, do not stand in favor of the seasonal-dummy approach. JEL classification: C53

متن کاملForecasting Seasonal Time Series∗
This chapter deals with seasonal time series in economics and it reviews models that can be used to forecast out-of-sample data. Some of the key properties of seasonal time series are reviewed, and various empirical examples are given for illustration. The potential limitations to seasonal adjustment are reviewed. The chapter further addresses a few basic models like the deterministic seasonali...
