Psychometric and Statistical Analysis Tools
Overview
Provides tools for psychometric and statistical analysis in social sciences, including functions for data preprocessing, factor analysis, reliability testing, descriptive statistics, visualization of Likert-scale items, measurement invariance analysis, and handling of multi-class imbalance. Facilitates advanced data analysis tasks commonly encountered in psychological and educational research. Includes an updated easy_invariance() function for ordinal data following Wu and Estabrook (2016) doi:10.1037/met0000051.
- Examples of the factor-analysis functions (
EFA_modern(),EFA_plot(),Standardized_solutions(),Standardized_solutions_cfa(),multi_cfa(),fit_index_Table(),plot_multi_sem(),combine_likert_sem(),safe_cfa(),cor_afe(),extract_fit(),factor_summary()and theboot_cfa*()/boot_efa*()families) now simulate Likert items from correlated latent factors. They used independentsample(1:5)draws, so the models had no common factor and could fail to converge on some platforms: theEFA_plot()example stopped with "fit measures not available if model did not converge" in the CRAN donttest check. - Version 1.2.3 was submitted to CRAN but withdrawn before review; its changes are included here.
