Forecasting Costa Rican inflation with machine learning methods

open access: yesLatin American Journal of Central Banking, 2020
We present a first assessment of the predictive ability of machine learning methods for inflation forecasting in Costa Rica. We compute forecasts using two variants of k-nearest neighbors, random forests, extreme gradient boosting and a long short-term ...

A comparative study on combinations of forecasts and their individual forecasts by means of simulated series

open access: yesActa Scientiarum: Technology, 2019
Over the years, several studies that compare individual forecasts with the combination of forecasts were published. There is, however, no unanimity in the conclusions. Furthermore, methods of combination by regression are poorly explored.

Forecasting droughts in East Africa [PDF]

open access: yesHydrology and Earth System Sciences, 2014
The humanitarian crises caused by the recent droughts (2008–2009 and 2010–2011) in East Africa have illustrated that the ability to make accurate drought forecasts with sufficient lead time is essential. The use of dynamical model precipitation forecasts

Sensitivity of Weights in Combining Forecasts [PDF]

open access: yesOperations Research, 1992
In the combination of forecasts, weighted averages that attempt to take into account the accuracy of the forecasts and any dependence among forecasts tend to perform poorly in practice. An important factor influencing this performance is the sensitivity, or instability, of the estimated weights used to generate the combined forecast.

Online Forecast Combination for Dependent Heterogeneous Data [PDF]

open access: yes, 2007
This paper studies a procedure to combine individual forecasts that achieve theoretical optimal performance. The results apply to a wide variety of loss functions and no conditions are imposed on the data sequences and the individual forecasts apart from
