a study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Person parameter estimation in the polytomous Rasch model
An important task in psychometric measurement is to identify the skills of persons, by accounting the difficulty degree of item responses in questionaries. The Item Response Theory (IRT) is the base for a valid measurement of the skills and the Rasch Model a well established probabilistic model, in the implementation of the theory. More recent extensions of the Rasch Model include the Partial C...
متن کاملa head parameter survey on mazandarani dialect and its effect(s) on learning english from ca perspective (on the basis of x-bar syntax)1
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
15 صفحه اولPairwise Rasch model item parameter recovery under sparse data conditions
In social science research the occurrence of missing values is a prevalent issue. In addition to that the use of multi-level response formats often results in low cell frequencies, especially under the condition of higher proportions of missing values and small datasets. This in turn may lead to problems for parameter identification in probabilistic item response models, applying the Conditiona...
متن کاملRandom parameter structure and the testlet model: extension of the Rasch testlet model.
The current Rasch testlet model (RT) assumes independence of the testlet effect and the target dimension. This article investigated the impact of the violation of that assumption on RT and the performance of an extended Rasch testlet model (ET) in which the random parameter variance-covariance matrix is estimated without any constraints. Our simulation results showed that ET was the same or sup...
