Chunk #26 — Methods — Data Analysis — Testing the association of CPA reporting patterns and alcohol-related behaviors: differences between EA and AA women
Time varying covariates included all CPA endorsement variables, regular smoking, cannabis dependence, MDD and CSA. Time invariant covariates included maternal and paternal alcohol-related problems and respondent CD. Covariate status was coded as negative in each year prior to the age at first occurrence and positive for that year and each subsequent year for each covariate considered. Huber-White robust standard errors were used to adjust for the non-independence of observations in siblings.
