Transformation of the STAR dataset as used in Table 8.2.1 of Angrist and Pischke (2008)
Format
A data frame containing 5743 observations and 6 variables. The first variable is from the original dataset, all other are created by Angrist and Pischke STAT code.

School ID in kindergarden (original variable, schoolidk in
STAR
)- pscore
The propensity score (computed by A & P)
- classid
The id of the class (computed by A & P)
- cs

Examples
data(STAR_MHE)
# Compute the group means:
STAR_MHE_means <- aggregate(STAR_MHE[, c('classid', 'pscore', 'cs')],
by=list(STAR_MHE$classid), mean)
# Regression of means, with weighted average:
reg_krug_gls <- lm(pscore~cs, data=STAR_MHE_means, weights=cs)
coef(summary(reg_krug_gls))[2,2]
