how to extract p-value in GenMatch function
Dear R-Users,
I have a problem on extracting T-Stat and P-Value. I have written R-code below
library("Matching")
data("lalonde")
attach(lalonde)
names(lalonde)
Y <- lalonde$re78
Tr <- lalonde$treat
glm1 <- glm(Tr~age+educ+black+hisp+married+nodegr+re74+re75,family=binomial,data=lalonde)
pscore.predicted <- predict(glm1)
rr1 <- Match(Y=Y,Tr=Tr,X=glm1$fitted,estimand="ATT", M=1,ties=TRUE,replace=TRUE)
summary(rr1)
> summary(rr1)
Estimate... 2624.3
AI SE...... 802.19
T-stat..... 3.2714
p.val...... 0.0010702

propensity score matching estimates?
...h" package to do propensity score matching. Here's some
example code that shows the problem that I'm having (much of this code is
taken from the Match package documentation):
*data(lalonde)
glm1 <- glm(treat~age + I(age^2) + educ + I(educ^2) + black +
hisp + married + nodegr + re74 + I(re74^2) + re75 + I(re75^2)
+
u74 + u75, family=binomial, data=lalonde)
X <- glm1$fitted
Y <- lalonde$re78
Tr <- lalonde$treat
# one-to-one matching with replacement (the "M=1" option).
# Estimating the treatment effect on the treated (the "estima...
