Decreases in Posttest Variance and The Measurement of Change
A Monte Carlo study was used to evaluate the effects of reductions in posttest variance on several methods for detecting predictors of change in a two-wave design. When the predictor was dichotomous, the analysis of covariance approach was compared to the analysis of variance on difference scores. For a continuous predictor, partial correlations, difference score correlations with the predictor...
متن کاملPortfolio performance evaluation in modified mean-variance models
The present study is an attempt toward evaluating the performance of portfolios and assets selecting using modified mean-variance models by utilizing a non-parametric efficiency analysis tool, namely Data Envelopment Analysis (DEA). Huge amounts of money are being invested in financial market. As a result, portfolio performance evaluation has created a great deal of interest among people. We kn...

متن کاملVariance of Entropy Decreases Under the Polar Transform
We consider the behavior of entropy of data elements as they are operated on by polar transforms. The data elements under consideration are pairs (X,Y ) where X is a binary random variable and Y is some side information about X . The entropy random variable for such a data element is defined as h(X|Y ) = − log pX|Y (X|Y ). The variance of entropy (varentropy) is defined as Var(h(X|Y )). A polar...
