چکیده

One test which is often used to investigate fit of the Rasch model to a dataset, is the Martin-Löf test for unidimensionality. This paper investigates whether (and when) its asymptotic chi-square distribution can be assumed to be appropriate. We also study the power of this test.

Implicational Scaling of Reading Comprehension Construct: Is it Deterministic or Probabilistic?

In English as a Second Language Teaching and Testing situations, it is common to infer about learners’ reading ability based on his or her total score on a reading test. This assumes the unidimensional and reproducible nature of reading items. However, few researches have been conducted to probe the issue through psychometric analyses. In the present study, the IELTS exemplar module C (1994) wa...

The effects of the violation of local independence assumption on the person measures under the Rasch model

Local independence of test items is an assumption in all Item Response Theory (IRT) models. That is, the items in a test should not be related to each other. Sharing a common passage, which is prevalent in reading comprehension tests, cloze tests and C-Tests, can be a potential source of local item dependence (LID). It is argued in the literature that LID results in biased parameter estimation ...

Martin-löf Reducibility and Cost Functions

Martin-Löf (ML)-reducibility compares K-trivial sets by examining the Martin-Löf random sequences that compute them. We show that every K-trivial set is computable from a c.e. set of the same ML-degree. We investigate the interplay between ML-reducibility and cost functions, which are used to both measure the number of changes in a computable approximation, and the type of null sets used to cap...
