ICC_AS_22032021: Script for calculating age- and sex-adjusted twin correlations.</div><div>3. ICC_AS_bySex_22032021: Same as above but splits output for each zyg group.</div><div>4. UniACE_AS_22032021: Fits an ACE model with the same covariate adjustments.</div><div>5. miFunctions.R: additional helper functions for fitting the model. This is automatically loaded within each of the other genetic scripts, so does not need to be run on its own.</div></div><div><br></div><div>In addition, the following scripts relate to the rest of the analyses in the figure:</div><div><br></div><div>1. iScience-D-12-03975-analyses-and-figures - RMarkdown file containing all of the descriptive analyses, code for reproducing figures and </div><div>2.
