the waiting time between children births are called tempo. this phenomenon plays a crucial role in the child and mother health. the purpose of the present study is determination of factors which influence this variable of interest. a significance level of 5% and power of 80% considered to calculate the required sample size for this cross sectional study. the sample size of 124 women determined ...

The paper studies the partial identifying power of structural single equation threshold crossing models for binary responses when explanatory variables may be endogenous. The paper derives the sharp identi…ed set of threshold functions for the case in which explanatory variables are discrete and provides a constructive proof of sharpness. There is special attention to a widely employed semipara...

security as a basic need for the members of society is in mutual relation to economic, social and cultural factors. today, this is of such importance in the progress of every society that it is considered as the prerequisite to any kind of development. social security has been defined as a complex – emotional – concept which is essential for protecting social groups and giving them the opportun...

  In an increasing number of practical situations, the quality of a process or product can be effectively characterized and summarized by a profile. A profile is usually a functional relationship between a response variable and one or more explanatory variables which can be modeled frequently using linear or nonlinear regression models. In this paper, we study the effect of non-normality on pro...

In this paper we address the problem of inducing Bayesian network models for regression from incomplete databases. We use mixtures of truncated exponentials (MTEs) to represent the joint distribution in the induced networks. We consider two particular Bayesian network structures, the so-called näıve Bayes and TAN, which have been successfully used as regression models when learning from complet...

We develop a misspecification test for the multiplicative two-component GARCHMIDAS model suggested in Engle et al. (2013). In the GARCH-MIDAS model a short-term unit variance GARCH component fluctuates around a smoothly timevarying long-term component which is driven by the dynamics of a macroeconomic explanatory variable. We suggest a Lagrange Multiplier statistic for testing the null hypothes...

We challenge the ‘big-bang’ approach to economic history offered by Acemoglu et al. (2011). The creation story in dispute is the French Revolution and the subsequent French occupation of a very small portion of Germany. We show that the four institutional reforms claimed to have spurred German industrialization have been incorrectly dated. These corrections nullify any explanatory power of the ...

environmental kuznets curve (ekc) is one of the known concepts in environmental economics developed dramatically over the last twenty years ago. one of the advances in studying the relationship between economic growth and environmental quality is concerning the spatial autocorrelation of ecological phenomena. the rationale behind spatial environmental kuznets curve (sekc) is similar to ekc incl...
