Multiple indicators, multiple causes (MIMIC) models are often employed by researchers studying the effects of an unobservable latent variable on a set of outcomes, when causes of the latent variable are observed. There are times, however, when the causes of the latent variable are not observed because measurements of the causal variable are contaminated by measurement error. The objectives of t...

This paper has two main goals. The first is to provide a framework for studying children well being utilising a capability approach. A list of capabilities for children in developing countries is drawn and its methodological justification is provided. The second aim is to suggest an econometric model to estimate child well being, utilising the list of capabilities provided in the first part of ...

Value assessment (valuation) of certain real properties is commonly required for a variety of purposes. In this article an approach to define an estimator of the value of a real property, with good statistical properties is proposed. This estimator reaches a consensus between the various available methods. The estimator proposed uses all available information optimally, including the informatio...

abstract in this paper, income per capita convergence hypothesis is tested in selected oic countries. for this purpose, we use the time series model and univariate kpss stationary test with multiple structural breaks (carrion-i-silvestre et al. (2005)) over the period 1950-2008. the results show that most oic countries could not catch up toward usa. although because of some positive term of tra...

The generalizability aspect of Construct validity, as proposed by Messick (1989), requires that a test measures the same trait across different samples from the same population. Differential Item functioning (DIF) analysis is a key component in the fairness evaluation of educational tests. University entrance exam for the candidates who seek admission into master's English programs (MEUEE) at I...
