Item fit was tested on the sample with complete response patterns using the polytomous
variant of the S-[chi square] index (Orlando & Thissen, 2000) with the Benjamini-Hochberg adjustment to control Type I error (Benjamini & Hochberg, 1995).
We used polytomous
regression models adjusted for current age (categories: < 50, 50-59, 60-69, 70-97 years), body mass index (BMI, < 25, 25-30, > 30), smoking status (current, past, never), current asthma (yes/no), and state (NC, IA) as well as for two current farming-related variables associated both with wheeze and pesticide use: days/ year mixed or applied any pesticides (0, 1-10, 11-365 days, based on the median days of annual pesticide application) and days/ year driving diesel tractors (0, < 31, 31-90, > 90 days, based on questionnaire categories) to evaluate the association between pesticide exposure and allergic and non-allergic wheeze.
Here, we use polytomous
regression analysis to identify clinical and epidemiological characteristics associated with unfavorable treatment outcomes among TB-HIV co-infected patients in Brazil.
Lastly, the fit statistic developed in this study is limited to dichotomous items and future research should focus on developing a similar measure for polytomous
The second half of the book proceeds through growth models that are nonlinear with respect to time, growth models that are nonlinear with respect to parameters, growth models that are nonlinear with respect to random coefficients, and applications to binary and ordered polytomous
Using multiple regression analysis to quantify the index and set sub-variables for polytomous
variables,[sup] we analyzed the impact of the major factors to inpatient medical expenditure comprehensively.
scales meanings, specifically in the case of socialization, each consecutive number in the scale represents a higher amount of socialization and the increase in scale points indicates a higher incidence of this aspect.
Pasquali (2012) considers that the scale's polytomous
items (items with more than two categories of response) require content analysis to verify whether it should be kept or discarded.
In case of polytomous
variables, the waste testing was used to complement these analyzes to identify associations between categories.
Dimensionality assessment of ordered polytomous
items with parallel analysis.
Error patterns on cognitive tasks: Applications of polytomous
item response theory and log-linear modeling.
The answers were scaled on a polytomous
items scale from 1 (totally disagree) to7 (totally agree).
