A simulation study was devised to evaluate the accuracy and precision of the GLIMMIX procedure when fitting the dichotomous Rasch model. The evaluation reviewed technicalities including item parameter recovery, standard error estimates, unstandardized and standardized fit indices produced by GLIMMIX. Factors manipulated in this study were The generating(More)
For research areas in education, psychology, public health, sociology, etc., the Rasch measurement models provide a framework of design and analysis tools that differ from classical true score theory (CTST). General statistical software packages (e.g., SPSS or STATA) have been considered either not suitable or difficult to program for the purpose of(More)
BACKGROUND The CHADS2 and CHA2DS2 scores are usually applied for stroke prediction in atrial fibrillation patients, and the Charlson comorbidity index (CCI) is a commonly used scale for assessing morbidity. The role in assessing mortality with score system in hemodialysis is not clear and comparisons are lacking. We aimed at evaluating CHADS2, CHA2DS2, and(More)
This study explores the possible association between the risk of ischemic stroke and conjugated equine estrogen (CEE) use in women who are over 55 years old and have diabetes. Data from the National Health Insurance system of Taiwan were used to identify 428 women over 55 years old with diabetes who used CEE (0.625 mg daily) from 2003 to 2009. For(More)
Traditionally, the principal goal of educational assessments is to evaluate students' academic achievement or proficiency in comparison to their peers or against promulgated standards. Both classical test theory (CTT) and item response theory (IRT) modeling frameworks provide measurement in the form of a summative estimate of the outcome variable. In recent(More)

Effect sizes are strongly encouraged to be reported in addition to statistical significance and should be considered in evaluating the results of a study. The choice of an effect size for ANOVA models can be confusing because indices may differ depending on the research design as well as the magnitude of the effect. Olejnik and Algina (2003) proposed the(More)
