Rasch analysis of the evaluation in Ayres sensory integration (EASI)
… For each of the 19 tests, I evaluated item fit statistics, rating scale fit statistics, person fit statistics, principal components analysis (PCA) of standardized residuals, differential item functioning (DIF) based on sex, person reliability index and strata. The dataset for this study …

A NEW SITE INDEX MODEL FOR INTENSIVELY MANAGED LOBLOLLY PINE (Pinus taeda) PLANTATIONS IN THE WEST GULF COASTAL PLAIN
… in the West Gulf Coastal Plain region. Data were fitted to six often commonly used SI functions models: Schumacher Algebraic Difference Approach (ADA) model, Chapman-Richards ADA model, Schumacher Generalized Algebraic Difference Approach (GADA) model, Chapman-Richards GADA model, Cieszewski GADA …

Detecting Rater Centrality Effect Using Simulation Methods and Rasch Measurement Analysis
… the point-measure correlation. The mean-square fit statistics, traditionally viewed as potential indicators of rater centrality, perform poorly in terms of differentiating central raters from normal raters. Along with the rater slope index, the mean-square fit statistics did not appear to be …

The Strength of Multidimensional Item Response Theory in Exploring Construct Space that is Multidimensional and Correlated
… well as along a second general order factor. The fit statistics that are generally applied to the 1-PL IRT model were not sensitive to the multidimensional item-level structure, reinforcing the requisite assumption of unidimensionality when applying the 1-PL IRT model.

Help seeking and the theory of planned behavior in college students : experiment and model testing
… in college students was examined. Based on model fit statistics the TPB adequately explained PHS in college students, but only after modifications were made to the measurement model.

A study of some life testing distributions
… gives relationships between a goodness-of-fit statistic based on a correlation coefficient and some well known and powerful goodness-of-fit statistics. Tables of critical values are given for complete and censored samples when the hypothesis to be tested is completely specified or when the …

Motivation, Marital Quality, Maternal Gatekeeping, Breadwinning, and Father Identity: Models Of Biological Fathers’ And Stepfathers’ Involvement In Childcare
… involvement in childcare differently. Although fit statistics did not meet the recommended structural equation modeling (SEM) values, parenting does appear to be different for biological fathers and stepfathers. Father identity was hypothesized to have a direct effect on fathering motivation for …

Antecedents and Consequences of Lifestyle Choice in Public Accounting
… hypothesized model demonstrated acceptable fit statistics and, generally, the hypotheses were supported. The results indicate that role stress as mediated by job burnout and its effect on psychological well-being will have a negative impact on job outcomes. However, the negative effects of …

An exploratory study of factors that influence student user success in an academic digital library.
… was tested and supported through model fit statistics. This model was recommended as a possible alternative model of user success. The dissertation also makes a number of recommendations for future research.

Deconstructing a domain into its cognitive attributes: test construction and data analysis
… framework for a college-level introductory statistics course. I begin with a review the current literature relating to cognitive diagnosis assessments and cognitive diagnosis models. Then I explain the procedure of deconstructing the course domain into a hierarchical arrangement of cognitive …

The application of a cognitive diagnostic model on the test of practical Chinese
… strengths and weaknesses. This study retrofits a CDM known as the Fusion model onto a non-diagnostic test data from the reading comprehension test of the Test of Practical Chinese (C.TEST). It focuses on the construction and modification of the Q-matrix which specifies the relationship …

Estimating Corn and Soybean Farm -Yield Distributions in Illinois
… and Anderson-Darling goodness-of-fit statistics, the logistic, Weibull and beta distributions consistently rank higher than the normal distribution. Goodness-of-fit results also suggest the danger of using a lognormal distribution to model farm-level yields. Finally, the results of …

The robustness of LISREL estimates in structural equation models with categorical data
… opposite directions. However, since goodness-of-fit statistics and standard errors are not available in LISREL when tetrachoric and polyserial correlations are used, the unbiased estimates are not of practical significance. Until alternative computer programs are available that employ …

An econometric model of the Japanese wool industry
… activity. Besides the traditional goodness of fit statistics for each equation, simulation experiments conducted with the final version of the model were used as a further tool for model evaluation, and where poor results were encountered attempts were made to isolate the cause, with particular …

The Sexual Communication of Socially Anxious Individuals in Intimate Relationships: Exploring the Connection Between Social Anxiety and Relationship Satisfaction
… Based on an examination of overall model fit statistics, chi square difference statistics, parameter coefficients, and correlation residuals, two models (one including fear of damaging the relationship and one without this variable) were retained. Both of the retained models, which …

Factors relating to the prevalence of autism
… conducted to analyze the data for goodness-of-fit to the theorized model. The variables studied as influences on the rate of autism were childhood poverty, ethnicity, access to psychological/psychiatric services, and access to advocacy, specifically geographic access to Autism of America …

Personality Predictors of Relationship Satisfaction among Engaged and Married Couples: An Analysis of Actor and Partner Effects
… trait, and all the models show excellent fit statistics. Findings show significant, negative actor and partner effects for neuroticism, depression, and impulsivity, and significant, positive actor and partner effects for kindness, flexibility, and self-esteem among both engaged and married …

College students' suicidal ideation: Testing the predictions of the existential - constructivist theory of suicide
… student sample and (b) compared the model fit of the ECTS to the ITS to assess which statistical model best explained suicidal ideation in college students. Survey data were collected electronically from 195 college students (i.e., aged 18 – 25) attending Purdue University. Data were …
