Having the sensitivity
and specificity
values, what software do you recommend that enables drawing the ROC
curve provided this data?
Thanks.

Nevertheless, I would recommend two R packages: ROCR for plotting (many options, very nice graphs) and colAUC
from caTools for calculating AUROC (rocket fast).
sensitivity
and specificity
values for different studies? Thanks

sensitivity
and specificity
. So, as you can imaging I JUST have values for those two variables for different studies, and trying to plot an ROC
curve. Provided that, what should I do to get an ROC curve correct? Thanks

TP
, FP
, FN
, and TN
. Do you think this is sufficient. There is a software called Meta-DiSc
that requires those values to draw a SROC
curve. By the way, is there a difference between SROC
and ROC
? Thanks

In addition to the previously mentioned packages, an other R package I would recommend to perform ROC Analysis and draw ROC curves is pROC. This package can perform multiclass AUC as defined by Hand and Till (2001).
