Effect of Dichotomization on the Latent Structure of Data [PDF]

Frontiers in Applied Mathematics and Statistics, 2021
We investigated whether dichotomous data showed the same latent structure as the interval-level data from which they originated. Given constancy of dimensionality and factor loadings reflecting the latent structure of data, the focus was on the variance ...

Addressing dichotomous data for participants excluded from trial analysis: a guide for systematic reviewers. [PDF]

PLoS ONE, 2013
Systematic reviewer authors intending to include all randomized participants in their meta-analyses need to make assumptions about the outcomes of participants with missing data.The objective of this paper is to provide systematic reviewer authors with a

A Comparison of Methods for Determining the Number of Factors to Retain with Exploratory Factor Analysis of Dichotomous Data

Psych, 2023
Exploratory factor analysis (EFA) is a very widely used statistical procedure in the social and behavioral sciences. This technique features in validity studies, as well as investigations of latent structure underlying observed measurements.

Checking assumptions: advancing the analysis of sex and gender in health sciences [PDF]

Biology of Sex Differences
Background Sex and gender are dissociable constructs, each including multiple components. Based on the analytic problems associated with dichotomising continuous variables, we aimed to synthesize a new approach to collecting and analysing sex and gender ...

Model Averaging Software for Dichotomous Dose Response Risk Estimation [PDF]

Journal of Statistical Software, 2008
Model averaging has been shown to be a useful method for incorporating model uncertainty in quantitative risk estimation. In certain circumstances this technique is computationally complex, requiring sophisticated software to carry out the computation ...

Association Between Individual Differences in Dichotomous Thinking and Current and Childhood High-Crime Environments

Evolutionary Psychology, 2023
The way people perceive the things around them is closely related to living in a complex and challenging social environment. Dichotomous thinking (preference for dichotomy, dichotomous belief, and profit-and-loss thinking), which classifies things in a ...

Autistic traits associated with dichotomic thinking mediated by intolerance of uncertainty

Scientific Reports, 2023
A recent cognitive model suggests that autistic individuals may experience dichotomous thinking patterns mediated by intolerance of uncertainty; however, empirical evidence to support this model is lacking.

Detecting Faking on Self-Report Measures Using the Balanced Inventory of Desirable Responding

Psych, 2023
We compared three methods for scoring the Balanced Inventory of Desirable Responding (BIDR) to detect faked responses on self-report measures: (1) polytomous, (2) dichotomous emphasizing exaggerating endorsement of socially desirable behaviors, and (3 ...
