[R] How to get mode (the most frequent value in distribution) ?
A sample from a continuous distribution most likely has no meaningful sample mode. Shown below is a way to estimate the location of mode from a kernel density estimate (using the locfit package):> x <- rnorm(50) > library(locfit)Locfit for R. August 3, 2000. (Updated for R 1.7.0, March 21, 2003) Attaching package 'locfit': The following object(s) are masked from package:stats : knots> x.den <- locfit(~x) > x[which.max(predict(x.den, newdata=x))][1] -0.615337 HTH, Andy> From: Gregor GORJANC > > Hello! > > I have a continous distribution and would like to get mode (the most > frequent value in distribution).
