Hi,
I wish to add confidence ellipse on my LDA result of the iris data set.
Therefore:
Is there statistical logic to do that as I only wish it to make the species
separation more visable?
How can I add it to the script below (ggplot):
require(MASS)
require(ggplot2)
iris.lda-lda(Species ~
Hi,
May be this helps:
require(MASS)
require(ggplot2)
iris.lda-lda(Species ~ Sepal.Length + Sepal.Width + Petal.Length +
Petal.Width, data = iris)
datPred-data.frame(Species=predict(iris.lda)$class,predict(iris.lda)$x)
library(ellipse)
dat_ell - data.frame()
for(g in levels(datPred$Species)){
Hi,
Thanks works like magic.
BTW
What is the confidence ellipses probability used?
