Correct application of the classical factorial F-test depends on normality and homogeneity of variance assumptions. If these assumptions are violated the type I error rate will be inflated and power of the test will be decreased. Therefore nonparamet

We study the problem of estimating higher-order stochastic volatility [SV ( p ) ] models. Due to the difficulty of evaluating the likelihood function, this remains a challenging problem, even in the relatively simple SV ( 1 ) case. We propose simple

Cuando se realiza la medición de una variable, es común que las estimaciones derivadas de una muestra de datos presenten una cantidad sustancial de sesgo. Algunos de los factores responsables son la asimetría de la distribución o la presencia de

The H-statistic is a robust test statistic in comparing the equality of two and more than two independent groups. This statistic is one of a good alternative to the F-statistic in the analysis of variance (ANOVA). The F-statistic is good only when th

A Decision Based Unsymmetrical trimmed modified Winsorized Variants for the removal of high density salt and pepper noise in images and videos is proposed. The algorithm initially checks for fixed outliers (0 or 255) in the images in a fixed 3x3 neig

The paper notices troublesome aspects of compiling industry statistics for the purpose of inter-enterprise comparison in corporate financial analysis. Whilst making a caveat that this issue is unbeknownst to practitioners and underrated by theorists,
