Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy // Tools for Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) for intersectional inequality research. Methods are described in Merlo (2018) doi:10.1016/j.socscimed.2017.12.026 and Evans et al. (2018) doi:10.1016/j.socscimed.2017.11.011. The package creates intersectional strata, fits multilevel MAIHDA models, estimates variance partition coefficients, proportional change in variance, stratum effects, and discriminatory-accuracy summaries, and provides diagnostic and presentation plots.
