Efficacy {CUtools} | R Documentation |
Estimate the efficacy of a biomarker
Description
The efficacy of a biomarker is defined by the treatment saved below a cut-off point minus the missclasified events.
Usage
Efficacy(Prob,yt,z)
Arguments
Prob |
A vector with the event probability values provided by the biomarker |
yt |
A vector with the actual event values |
z |
The misclassification rate at which the effectiveness of the marker will be estimated. |
Details
Prob must be a numeric vector with values between 0 and 1, yt a numeric vector with dichotomic values 0/1 and z a numeric value between 0 and 100
Value
The returned object contains the Efficacy of the biomarker Prob at a specific z rate of missclasified events
Efficacy |
Efficacy of the biomarker Prob at a specific z rate of missclasified events |

Examples
###We generate a marker to serve as an example
Prob<-c(rnorm(10000,0.4,0.1),rnorm(10000,0.5,0.05))
yt<-rep(c(0,1),c(10000,10000))
#We choose a rate of 10% for misclassified events.
Efficacy(Prob=Prob,yt=yt,z=10)
