摘要:In this paper, quarterly point forecasts and prediction intervals are built for unemployment rate in Romania. The point forecasts are based on some updated vector-autoregressive models (VAR models) and on a Bayesian VAR model. These point predictions and the root mean squared- error corresponding to the forecasts of the previous 4 quarters are used to construct the intervals. According to root mean squared-error, mean error and mean absolute error, VAR model outperformed the Bayesian approach in terms of forecast accuracy. 75% of the intervals based on VAR models included the quarterly forecasts on the horizon 2011:01-2014:04. The probability of these intervals to include the actual values is higher than 0.8, according to likelihood ratio and chi-square tests.
