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 ...
متن کاملViolations of local stochastic independence exaggerate scalability in Mokken scaling analysis of the Chinese Mandarin SF-36
BACKGROUND Previous work using Mokken scaling analysis with the SF-36 has found subscales appearing to show excellent Mokken scaling properties. However, the values of scalability of the subscales are very large, raising the possibility that these are artificially high and this may result from violations of local stochastic independence between items. OBJECTIVES To analyse selected items from...

متن کاملAllais Paradoxes Can be Reversed by Presenting Choices in Canonical Split Form
This paper tests Birnbaum’s (2004) theory that the constant consequence paradoxes of Allais are due to violations of coalescing, the assumption that when two branches lead to the same consequence, they can be combined by adding their probabilities. Rank dependent utility and cumulative prospect theory imply that the Allais paradoxes are due to violations of restricted branch independence, a wea...

But it is very difficult to put the two together because politics belongs to the realm of power and domination, and the politician does not involve himself too much in moral concepts that are cumbersome for his purposes in order ...
