Outdated document of PCA.

[Losses]

The DataArrays is no longer maintained, constructing dataset should use

Xte = convert(Matrix,iris[2:2:end,1:4])'

but not:

Xte = convert(Array,DataArray(iris[2:2:end,1:4]))'

Thanks for the report. Would you make a pull request to fix this? You can edit the file directly on GitHub.

@nalimilan Okay, I'll do it this weekend if I have enough free time :D

It looks like the edit is in github:

https://github.com/JuliaStats/MultivariateStats.jl/blob/master/docs/source/pca.rst

but hasn't made its way to the documentation:
