Risk Assessment Plots
Crucial to evaluating the value of a new biomarker (variable) to a pre-existing risk model is whether it increases the calculated risk of those with the disease (event/outcome) and decreases the calculated risk of those without. In the past 4 years two new statistics - the IDI and NRI have been proposed. Risk_Assessment_Plot calculates those stats along with several others and produces a plot to visualize them. I published an explanation of this plot and the associated metrics recently - it is available Open Access: http://cjasn.asnjournals.org/content/early/2012/05/24/CJN.09590911.full
My first submission - perhaps not pretty, but useful I hope.
