A Simple Forecasting Accuracy Criterion Under Rational Expectations; Evidence From the World Economic Outlook and Time Series Models

Barrionuevo, José M. - International Monetary Fund (IMF) - 1992

A simple criterion based on the properties of the forecast error is presented to evaluate the accuracy of forecasts. The efficiency conditions of an optimization problem are used to show that under rational expectations the standard statistical conditions are necessary, but not sufficient to...

Simulation of Errors in Linear Regression: An Approach Based on Fixed Percentage Area

Imon, Rahmatullah - In: Computational Statistics 18 (2003) 3, pp. 521-531

the random enors of this model. In the simulation of random errors it is a common practice to generate data from a target … distort the non-normal shape of any longer-tailed distribution. In this paper we propose a new approach of simulating random … errors by fixing the lower percentage area of any target distribution which, we believe, will allow the longer …
