Abstract:
When item scores are ordered categorical, categorical omega can be computed based on the parameter estimates from a factor analysis model using frequentist estimators such as diagonally weighted least squares. When the sample size is relatively small and thresholds are different across items, using diagonally weighted least squares can yield a substantially biased estimate of categorical omega. In this study, we applied Bayesian estimation methods for computing categorical omega. The simulation study investigated the performance of categorical omega under a variety of conditions through manipu

Abstract:
AbstractShelah has provided sufficient conditions for an ${\Bbb L}_{\omega _1 ,\omega } $-sentence ψ to have arbitrarily large models and for a Morley-like theorem to hold of ψ. These conditions involve structural and set-theoretic assumptions on all the ${\aleph _n}$’s. Using tools of Boney, Shelah, and the second author, we give assumptions on ${\aleph _0}$ and ${\aleph _1}$ which suffice when ψ is restricted to be universal:Theorem. Assume ${2^{{\aleph _0}}} < {2^{{\aleph _1}}}$. Let ψ be a universal ${\Bbb L}_{\omega _1 ,\omega } $-sentence.(1)If ψ is categorical in ${\aleph _0}$ and $1

Abstract:
Мы исследуем реляционные базы данных над упорядоченной областью определения с некоторыми дополнительными отношениями – типичным примером является упорядоченное множество рациональных чисел с операцией сложения. В фокусе наших исследований запросы первого порядка, инвариантные относительно перестановок, сохраняющих порядок, – такие запросы называются порядково-генерическими. Установлено, что для некоторых областей порядково- генерические запросы первого порядка сводятся к запросам чистого порядка. Здесь мы доказываем теорему сводимости над почти омега-категоричной слабо о-минимальной областью о
