asm {Fstability}

Adjusted Stability Measure

Description

Calculates feature stability using asm.

Usage

asm(x,y)

Arguments

x

A dataframe where each column is a subset.

y

A vector of the original set.

Details

This formula to calculate feature selection stability comes from:

Lustgarten, J. L., Gopalakrishnan, V., & Visweswaran, S. (2009). Measuring Stability of Feature Selection in Biomedical Datasets. AMIA Annual Symposium Proceedings, 2009, 406–410.

Examples

x<-c(1,2,3,4)
y<-c(3,4,5)
z<-c(2,3,4,5,6)
T<-lump(x,y,z)
A<-c(1,2,3,4,5,6,7)
asm(T,A)
