Robust Wilks' Statistic based on RMCD for One-Way Multivariate Analysis of Variance (MANOVA) [PDF]

open access: yes, 2017
The classical Wilks' statistic is the most using for testing the hypotheses of equal mean vectors of several multivariate normal populations for one-way MANOVA. It is extremely sensitive to the influence of outliers.

The Role of Affective Experiences and Exercise Motivation as Predictors of Physical Activity Intentions Among Individuals With Overweight and Obesity

open access: yesObesity Science & Practice
Background Evidence suggests that affective experiences of exercise may underlie motivation for physical activity (PA) and PA itself. Affective experiences involve emotional responses, such as pleasure or displeasure related to PA.

Non-stationary Variance and Volatility Causality [PDF]

open access: yes
This paper aims to describe bias estimates when non-stationary variance is not detected. We first present a theoretical multivariate GARCH model with structural changes in variance. Then we describe the non-stationary variance and Volatility Causality in

SAS/IML Macros for a Multivariate Analysis of Variance Based on Spatial Signs [PDF]

open access: yes
Recently, new nonparametric multivariate extensions of the univariate sign methods have been proposed. Randles (2000) introduced an affine invariant multivariate sign test for the multivariate location problem. Later on, Hettmansperger and Randles (2002)

Multivariate analysis of variance with fewer observations than the dimension

open access: yes
In this article, we consider the problem of testing a linear hypothesis in a multivariate linear regression model which includes the case of testing the equality of mean vectors of several multivariate normal populations with common covariance matrix ...

Classical and robust methods of MANOVA analysis

open access: yes, 2019
Daudzdimensiju dispersiju analīze (MANOVA) tiek pielietota situācijās, kad tiek mērīti vairāki mainīgie katrai eksperimentālai vienībai. Darbā aplūkota teorija par klasisko MANOVA metodi un robusto MANOVA metodi, to pieņēmumiem un pielietojumiem.
