pROC: display and analyze ROC curves in R and S+. pROC is a set of tools to visualize, smooth and compare receiver operating characteristic (ROC curves). (Partial) area under the curve (AUC) can be compared with statistical tests based on U-statistics or bootstrap. Confidence intervals can be computed for (p)AUC or ROC curves. More screenshots and examples Find us on: If you use pROC in. I've been doing some classification with logistic regression in brain imaging recently. I have been using the ROCR package, which is helpful at estimating performance measures and plotting these measures over a range of cutoffs. The prediction and performance functions are the workhorses of most of the analyses in ROCR I've been doing. For those [ * ROC curves : using package pROC : DUMMY EXAMPLE*. Ask Question Asked 7 years, 3 months ago. Active 7 years, 3 months ago.

So I request anyone here who could explain me about it with respect to my dummy example below. So lets say I have a microarray data as follows. For example, SAS, a very popular commercial tool is easy to use, but expensive; R, on the other hand, is free and powerful, but requires programming/tool expertise, due to lack of accountability and minimum support. Continued efforts towards enabling usage of multiple languages in a single tool has allowed users proficient in a particular technology/language to also benefit from the advantages.

- Examples: MI Procedure. The Fish data described in the STEPDISC procedure are measurements of 159 fish of seven species caught in Finland's lake Laengelmavesi. For each fish, the length, height, and width are measured. Three different length measurements are recorded: from the nose of the fish to the beginning of its tail (Length1), from the nose to the notch of its tail (Length2), and from.
- In the above example, as the curve moves away from the grey diagonal line towards top left corner of the graph, sensitivity and specificity increase, and at the same time, the area under the graph increases. Hence, the models with higher performance will show the ROC curve closer to the top left corner, increasing the area under curve. To compare with the above result, a larger decision tree.
- PROC TRANSPOSE helps to reshape data in SAS. This tutorial explains the basic and intermediate applications of PROC TRANSPOSE with examples. It's a very powerful procedure when you need to change the shape of the data. For example, you have data in vertical (long) format and you are asked to change it to horizontal (wide) format. It can be done via data step as well but it would be a complex.
- This is the main function of the pROC package. It builds a ROC curve and returns a roc object, a list of class roc. This object can be prin ted, plot ted, or passed to the functions auc , ci , smooth.roc and coords . Additionally, two roc objects can be compared with roc.test

Compute the area under the ROC curve. This function computes the numeric value of area under the ROC curve (AUC) with the trapezoidal rule. Two syntaxes are possible: one object of class roc, or either two vectors (response, predictor) or a formula (response~predictor) as in the roc function. By default, the total AUC is computed, but a portion of the ROC curve can be specified with.
