Description
De-identified participant-level data (N = 960 young adults from three U.S. and Canadian samples) and R Markdown analysis code testing whether vocal fundamental frequency and formant frequencies are associated with heterozygosity at the major histocompatibility complex (MHC), height, and sex. The dataset includes vocal acoustic measures, height, weight, age, sex, sample, MHC and genome-wide heterozygosity indices, and genetic principal components. The code reproduces all analyses, tables and figures. See README.md for file and variable descriptions.
