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,
