A Comprehensive Look at the Empirical Performance of Equity Premium Prediction,”
, 2004
"... Abstract Economists have suggested a whole range of variables that predict the equity premium: dividend price ratios, dividend yields, earningsprice ratios, dividend payout ratios, corporate or net issuing ratios, bookmarket ratios, beta premia, interest rates (in various guises), and consumption ..."

), and consumptionbased macroeconomic ratios (cay). Our paper comprehensively reexamines the performance of these variables, both insample and outofsample, as of 2005. We find that [a] over the last 30 years, the prediction models have failed both insample and outofsample; [b] the models are unstable
Approximation schemes for covering and packing problems in image processing and VLSI
 J. ACM
, 1985
"... A unified and powerful approach is presented for devising polynomial approximation schemes for many strongly NPcomplete problems. Such schemes consist of families of approximation algorithms for each desired performance bound on the relative error c> 0, with running time that is polynomial whe ..."

that is introduced here, referred to as the shifting strategy, is applicable to numerous geometric covering and packing problems. The method of using the technique and how it varies with problem parameters are illustrated. A similar technique, independently devised by B. S. Baker, was shown to be applicable

"... Abstract. We define a class of dynamical systems on the sphere analogous to the baker map on the torus. The classical maps are characterized by dynamical entropy equal to ln 2. We construct and investigate a family of the corresponding quantum maps. In the simplest case of the model the system does ..."

Quantitative methods in psychology: A power primer
 Psychological Bulletin

"... One possible reason for the continued neglect of statistical power analysis in research in the behavioral sciences is the inaccessibility of or difficulty with the standard material. A convenient, although not comprehensive, presentation of required sample sizes is provided here. Effectsize indexe ..."

size indexes and conventional values for these are given for operationally defined small, medium, and large effects. The sample sizes necessary for .80 power to detect effects at these levels are tabled for eight standard statistical tests: (a) the difference between independent means, (b) the significance

This paper describes our initial research into the use of the P300 event related potential as a control signal in a computer interface for lockedin patients. These experiments are directed toward development of a device which uses the occurrence of a P300 to control motion of a cursor on a computer screen. Simultaneous targetdetection tasks are presented in four compass positions (N, E, S, W) on a computer screen. The subject is instructed to detect targets in one of the positions corresponding to the intended direction of cursor movement. EEG signals from scalp electrodes at Fz, Cz and Pz are collected and averaged for targets in each of the four locations and the direction of movement is indicated by the highest P300 peak amplitude. Variables such as target ontime, ISI, nulltarget inclusion, and trial averaging are manipulated and the results are discussed in terms of a rate vs. accuracy tradeoff.
