Investigating sources of withinand between-group differences and measurement invariance (MI) across groups is fundamental to any meaningful group comparison based on observed test scores. It is shown that by placing certain restrictions on the multigroup confirmatory factor model, it is possible to investigate the hypothesis that withinand between-group differences are due to the same factors. ...
aim of this study was to examine factorial invariance of the 20-item Positive and Negative Affect Schedule-Farsi version (PANAS) among male and female university students. A total of 371 undergraduate students (183 males and 188 females) at Shahid Beheshti University completed the Farsi version of the PANAS. First, two-factor model consisted on positive and negative affect were applied to the t...
Solution concepts in cooperative games are based on either cost games or benefit games. Although cost games and benefit games are strategically equivalent, that is not the case in general for solution concepts. Motivated by this important observation, a new property called invariance property with respect to benefit/cost allocation is introduced in this paper. Since such a property can be regar...
Invariance principles is one of the ways to summarize sample information and by these principles invariance or equivariance decision rules are used. In this paper, first, the methods for finding the maximal invariant function are introduced. As a new method, maximal invariant statistics are constructed using equivariant functions. Then, using several equivariant functions, the maximal invariant...
in this short review we look at recent advances in schramm-loewner evolution (sle) theory and its application to critical phenomena. the application of sle goes beyond critical systems to other time dependent, scale invariant phenomena such as turbulence, sand-piles and watersheds. through the use of sle, the evolution of conformally invariant paths on the complex plane can be followed; hence a...
We assess within-study invariance of key UTAUT scales considering a total of six respondent group characteristics: five variables pertaining to users’ two technology engagement facets (prior technology knowledge and technology usage pattern) and one variable pertaining to their gender. Data collected from 250 respondents about their perceptions and usage of online blogs were analyzed to test si...
