Hi ,
I am new to Twin data analysis and would like to get help on how to adjust for covariates ( Age and Gender) in TWIN ACE model to estimate the genetic and environmental variance from the total molecular phenotypic variance . What modifications are needed in the script UnivariateTwinAnalysis_MatrixRaw.R for age and gender adjusted estimation of A, C and E .
Any insight would be of great help.
