Comparing Predictive Accuracy

by Francis X. Diebold, Roberto S. Mariano - JOURNAL OF BUSINESS AND ECONOMIC STATISTICS, 13, 253-265 , 1995
"... We propose and evaluate explicit tests of the null hypothesis of no difference in the accuracy of two competing forecasts. In contrast to previously developed tests, a wide variety of accuracy measures can be used (in particular, the loss function need not be quadratic, and need not even be symmetri ..."

TESTING FOR DIFFERENCES IN PREDICTIVE ACCURACY

by Eva Ferreira, Winfried Stute
"... In this paper we provide new tests for the difference in predictive accuracy of two prog-nostic factors X1 and X2 on a common output Y. Given a set of independent replicates of (X1,X2,Y), we split this sample into a learning part for estimating the unknown regression functions, and a validation part ..."

Discussion: Unification and Predictive Accuracy*

by Malcolm R. Forster, Especially Paul Anders, W. John Koolage, Greg Novack
"... Wayne Myrvold (2003) has captured an important feature of unified theories, and he has done so in Bayesian terms. What is not clear is whether the virtue of such unification is most clearly understood in terms of Bayesian confirmation. I argue that the virtue of such unification is better understood ..."

Generality is Predictive of Prediction Accuracy

by Geoffrey I. Webb, Damien Brain
"... During knowledge acquisition multiple alternative potential rules all appear equally credible. This paper addresses the dearth of formal analysis about how to select between such alternatives. It presents two hypotheses about the expected impact of selecting between classification rules of differing ..."

of differing levels of generality in the absence of other evidence about their likely relative performance on unseen data. It is argued that the accuracy on unseen data of the more general rule will tend to be closer to that of a default rule for the class than will that of the more specific rule. It is also

A study of branch prediction strategies

by E. Smith, Arden Hills Minnesota - In Proceedings of the 8th annual symposium on Computer Architecture
"... In high-performance computer systems. performance losses due to conditional branch instructrons can be minrmized by predicting a branch outcome and fetching, decoding, and/or issuing subsequent instructions before the actual outcome is known. This paper discusses branch prediction strategies wrth th ..."

Predictive Accuracy as an Achievable Goal of Science

by Malcolm R. Forster
"... What has science actually achieved? A theory of achievement should (1) define what has been achieved, (2) describe the means or methods used in science, and (3) explain how such methods lead to such achievements. Predictive accuracy is one truth-related achievement of science, and there is an explan ..."

Robust Tests of Predictive Accuracy

by Elvezio Ronchetti Y , 2004
"... We propose robust counterparts to tests of equal forecast accuracy such as those proposed by Diebold and Mariano (1995) and West (1996). We illustrate the robustness problem and evaluate the size and the power properties of the classical and robust tests under various types of deviations from model ..."
