A Measure of Departure from Average Marginal Homogeneity for Square Contingency Tables with Ordered Categories

open access: yesRevstat Statistical Journal, 2011
For the analysis of square contingency tables, Tomizawa, Miyamoto and Ashihara (2003) considered a measure to represent the degree of departure from marginal homogeneity.

Bayesian analysis of Ecological Momentary Assessment (EMA) data collected in adults before and after hearing rehabilitation

open access: yesFrontiers in Digital Health, 2023
This paper presents a new Bayesian method for analyzing Ecological Momentary Assessment (EMA) data and applies this method in a re-analysis of data from a previous EMA study.

Testing Measurement Invariance with Ordinal Missing Data: A Comparison of Estimators and Missing Data Techniques [PDF]

open access: yes, 2019
Ordinal missing data are common in measurement equivalence/invariance (ME/I) testing studies. However, there is a lack of guidance on the appropriate method to deal with ordinal missing data in ME/I testing.

Multimodal Affect Models: An Investigation of Relative Salience of Audio and Visual Cues for Emotion Prediction

open access: yesFrontiers in Computer Science, 2021
People perceive emotions via multiple cues, predominantly speech and visual cues, and a number of emotion recognition systems utilize both audio and visual cues.

Maximally selected chi-square statistics for at least ordinal scaled variables [PDF]

open access: yes, 2005
The association between a binary variable Y and a variable X with an at least ordinal measurement scale might be examined by selecting a cutpoint in the range of X and then performing an association test for the obtained 2x2 contingency table using the ...

Mixture Models for Ordinal Data [PDF]

open access: yesSociological Methods & Research, 2010
Cumulative probability models are widely used for the analysis of ordinal data. In this article the authors propose cumulative probability mixture models that allow the assumptions of the cumulative probability model to hold within subsamples of the data. The subsamples are defined in terms of latent class membership.

Interval-Valued Intuitionistic Fuzzy Synthetic Measure (I-VIFSM) Based on Hellwig’s Approach in the Analysis of Survey Data

open access: yesMathematics, 2021
Several complex phenomena are measured with the use of tools in the form of a questionnaire where the values of criteria are assessed by the respondents using ordinal scales.

Fruit production is influenced by tree size and size‐asymmetric crowding in a wet tropical forest

open access: yesEcology and Evolution, 2019
In tropical forest communities, seedling recruitment can be limited by the number of fruit produced by adults. Fruit production tends to be highly unequal among trees of the same species, which may be due to environmental factors.

On Two Mixture-Based Clustering Approaches Used in Modeling an Insurance Portfolio

open access: yesRisks, 2018
We review two complementary mixture-based clustering approaches for modeling unobserved heterogeneity in an insurance portfolio: the generalized linear mixed cluster-weighted model (CWM) and mixture-based clustering for an ordered stereotype model (OSM).

Comparing distributions of ordinal data [PDF]

open access: yesThe Stata Journal: Promoting communications on statistics and Stata, 2020
To compare distributions of ordinal data such as individuals’ responses on Likert-type scale variables summarizing subjective well-being, we should not apply the toolbox of methods developed for cardinal variables such as income. Instead, we should use an analogous toolbox that accounts for the ordinal nature of the responses.
