This study contributes to passive portfolio management by comparing four ways for asset allocation. Index investing, mean-variance optimization, equal-weighting and semi-variance optimization are compared as part of the investment strategy aimed at outperforming Dow Jones Industrial Average (DJIA). The best way allocate assets was portfolios looking minimum semi-variance. Yield spreads below pe...

Normalization operations are essential for state-of-the-art neural networks and enable us to train a network from scratch with large learning rate (LR). We attempt explain the real effect of Batch (BN) perspective variance transmission by investigating relationship between BN Weights (WN). In this work, we demonstrate that problem shift average gradient will amplify every convolutional (conv) l...

OBJECTIVE This study investigated whether there was a significant difference in the cumulative grade point average (GPA) of individual students at the end of their first 3 professional years in the doctor of pharmacy curriculum as a function of previous years in college. METHODS The cumulative GPA for the first- through third-professional years was calculated for the 2004-2007 graduating clas...

Multi-point wave observations on Cluster spacecraft are used to infer the dispersion relation of electromagnetic ion cyclotron (EMIC) waves. In this study we use a phase differencing method and observations from STAFF and WHISPER during a well-studied event of 30 March 2002. The phase differencing method requires the knowledge of the direction of the wave vector, which was obtained using minimu...

ABSTRACT. In paired randomized experiments units are grouped in pairs, often based on covariate information, with random assignment within the pairs. Average treatment effects are then estimated by averaging the within-pair differences in outcomes. Typically the variance of the average treatment effect estimator is estimated using the sample variance of the within-pair differences. However, con...
