Recent methodological developments building on partial least squares (PLS) techniques and related ideas have significantly contributed to bridging the gap between factor-based and composite-based structural equation modeling (SEM) methods. PLS-SEM is extensively used in the field of e-collaboration, as well as in many other fields where multivariate statistical analyses are employed. We compare...

This paper investigates the relationship between inflation and inflation uncertainty for the period of 1990-2009 by using monthly data in the Iranian economy. The results of a two-step procedure such as Granger causality test which uses generated variables from the first stage as regressors in the second stage, suggests a positive relation between the mean and the variance of inflation. However...

factor demand behavior such as energy demand has an important role in the economic analysis. this issue is a major concern in the developing countries (e.g. iran) which are benefited from vast energy resources. in this paper, the third generation of factor demand models is used to analyze the behavior of capital adjustment in the iranian manufacturing industries. the dataset covers the two-digi...

Little is known about long-term outcomes of reading problems in childhood on affective symptoms across the life course. The aim this research was to test longitudinal associations between and from adolescence early old age. Data were National Survey Health Development (British 1946 birth cohort). A measure available at age 11. Affective assessed ages 13, 15, 35, 43, 53, 60–64 69. Path analyses ...

Emerging packet-switched architectures, such as Internet telephony, introduce new complications to manage the Feature Interaction (FI) problem. Those difficulties are generated by sophisticated technical properties. The latter are mainly distribution of data and control, equipment heterogeneity, network openness to third party service providers, and end user programmability. Our solution approa...

This paper deals with the issues of identification and estimation in a bivariate simultaneous equations system with endogenous dummy variables and continuous observable dependent variables. The model is an extension of threshold models to a simultaneous equations framework. Depending on the sign of relevant parameters, for a range of values of the exogenous variables the relationship between th...

Researchers conducting longitudinal data analysis in psychology and the behavioral sciences have several statistical methods to choose from, most of which either require specialized software conduct or advanced knowledge inform selection correct model options (e.g., correlation structure). One simple alternative conventional is calculate area under curve (AUC) from repeated measures then use th...
