Purpose
Calculate and display ROC curves for PLSDA model.
Synopsis
- roc = plsdaroc(model,ycol,options)
Description
ROC curves can be used to assess the specificity and sensitivity possible with different predicted y-value thresholds for a PLSDA model. Inputs are a PLSDA model model, an optional index into the y-columns used in the model ycol [default = all columns], and an options structure. Output is a dataset with the sensitivity/specificity data roc.
Options
- plots : [ 'none' | {'final'}] governs plotting on/off
