MCS is mental health component summary score.

Education is centered at 12, and birth year is centered at 1960 so the constant is interpretable.

Education is coded linearly as years of education until 13 years, and flat thereafter (i.e. everything after 13 years of schooling is recoded as 13 years because we found this specification was the best fit for the MCS data). A 1-unit increase in education is a 1-year increase in schooling until 13 years.
