Abstract
Forecasting macroeconomic variables using many predictors is considered. Model selection and model reduction approaches are compared. Model se-lection includes heuristic optimisation of information criteria that include: simulated annealing, genetic algorithms, MC3 and sequential testing. Model reduction employs the methods of principal components, partial least squares and Bayesian shrinkage regression. The problem of unbalanced datasets is discussed and potential solutions are suggested. An out-of-sample forecast-ing exercise provides evidence that these methods are useful in predicting the growth rate of quarterly GDP and monthly inflation.File | Dimensione | Formato | |
