Hi - I am using polr. I can get a result from polr fit by calling

result.plr <- polr(formula, data=mydata, method="probit");

However, from the 'result.plr', how can I access standard error of the estimated coefficients as well as the t statistics for each one of them?

What I would like to do ultimately is to see which coefficients are not significant and try to refit the model again by excluding those variables out. I would appreciate if anyone could give some hint on this. Thank you.
