Calculate the Area under the R_NX(ln K), used in Lee et. al. (2015). Note
that despite the name, this does not weight the mean by the logarithm, but by
1/K. If explicit weighting by the logarithm is desired use weight =
"log" or weight = "log10"
Arguments
- object
of class dimRedResult
- weight
the weight function used, one of
c("inv", "log", "log10")
Details
The naming confusion originated from equation 17 in Lee et al (2015) and the name of this method may change in the future to avoid confusion.
