Hi all
is there a macro/code that mimics in SAS what pROC and bootLR do in R?
my aim is to calculate bootstrap threshold, sensitivity, specificity, LT+ and LR- along with 95% CI
Tks!

What do pROC and bootLR do?
Normally, a likelihood ratio is computed to test to see if a statistic is significantly different than some quantity ... what statistic is being tested, and in what context?
Normally, bootstrap confidence intervals are computed to see some measure of variability of a particular statistic ... what statistic is being tested, and in what context?
I’m testing if a new parameter is predictive of an outcome.
Some sort of regression??? A decision tree??? A Neural Network??? What is the exact type of model?
Other authors did the same and provided AUC, cut-off (with corresponding sensibility, specificity, LR+ and -) calculated after bootstrapping
Logistic regression?? Decision tree?? Neural Network?? Other???
