A potential question away from this process is the fact they assumes covariates have the same outcomes (coefficients) to your results of attract across all of the racial combos.
We investigated variations in delivery consequences (i.elizabeth., birthweight, LBW rates, 5-moment Apgar rating, and newborn death) to have babies produced to non-Latina Light mothers and you may non-Latina Black dads (henceforth, Light and you can Black colored relate to non-Hispanic White and you will low-Latina Black) and people produced to help you Light mothers and fathers from 6 most other selected racial/cultural groups.
