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$fitted,estimand="ATT", M=1,ties=TRUE,replace=TRUE)
summary(rr1)
> summary(rr1)
Estimate... 2624.3
AI SE...... 802.19
T-stat..... 3.2714
p.val...... 0.0010702
Original number of observations.............. 445
Original number of treated obs............... 185
Matched number of observations............... 185
Matched number of observations (unweighted). 344
In above output, I can extract "Estimate" and "AI SE" with below code:
rr1$est
rr1$se
But the problem is I could not extract T-statistic and P-value from the above
output.
Could you please someone help me to resolve this problem?
Thanking you,
Best Regards,
