A multiplicative model is proposed for analyzing multifactor experiments which are conducted to study the effect of changes in the levels of the factors on the variance of a chance variable. The model ...

Reduced rank approximation of matrices by Householder-Young methods is shown to be equivalent to fitting of a bilinear (multiplicative) model and to projection onto an optimally chosen subspace. The ...

To capture the "long-memory" effect in volatility, a multiplicative component conditional autoregressive range (MCCARR) model is proposed. We show theoretically that the MCCARR model can capture the ...

Clinical utility of expanded screening of the KRAS and NRAS genes for Metastatic Colorectal Cancer: Evaluation of the CRC RAScan tumor test as a companion diagnostic to determine efficacy of anti-EGFR ...

In a test of equivalence, a treatment mean and a reference mean are compared to each other. Equivalence is taken to be the alternative hypothesis, and the null hypothesis is nonequivalence. The model ...

A comparison of two models for stock market prediction shows clear differences in their accuracy, depending on the length of the forecasting period. Understanding stock market returns hinges on ...
