Details

This data set was obtained using:

here <- age <= 40 & re74<=5000 & re75 <= 5000 & re78 < 30000 nsw74psidA <- nsw74psid1[here, ]

Examples

table(nsw74psidA$trt)

A1.lm <- lm(re78 ~ trt + (age + educ + re74 + re75) + (black +
      hisp + marr + nodeg), data = nsw74psidA)
summary(A1.lm)$coef

discA.glm <- glm(formula = trt ~ age + educ + black + hisp +
  marr + nodeg + re74 + re75, family = binomial, data = nsw74psidA)
A.scores <- predict(discA.glm)

options(digits=4)
overlap <- A.scores > -3.5 & A.scores < 3.8
A.lm <- lm(re78 ~ trt + A.scores, data=nsw74psidA, subset = overlap)
summary(A.lm)$coef
