Provides a set of tools for estimating hierarchical linear models and effect sizes based on data from single-case designs. Functions are provided for calculating standardized mean difference effect sizes that are directly comparable to standardized mean differences estimated from between-subjects randomized experiments, as described in Hedges, Pustejovsky, and Shadish (2012) doi:10.1002/jrsm.1052; Hedges, Pustejovsky, and Shadish (2013) doi:10.1002/jrsm.1086; Pustejovsky, Hedges, and Shadish (2014) doi:10.3102/1076998614547577; and Chen, Pustejovsky, Klingbeil, and Van Norman (2023) doi:10.1016/j.jsp.2023.02.002. Includes an interactive web interface.
