Re: CVA in MorphoJ vs LDA in R

[Stefan Schlager]

Dear Louis and Martha,

the difference between lda in R and a cva - is that lda uses the 
covariance matrix and not the pooled within group covariance matrix.

greetings

Stefan

BTW.: at the moment i am working on a Rpackage that implements sliding 
of surface and curve semilandmarks (on 3D-meshes including reprojection 
- using a very fast command line app coded on the base of vcglib 
(meshlab)), it also contains a cva and some tools for importing and 
exporting meshes that can be rendered by the rgl package and for 
importing data from and to "landmark" etc..... if someone is interested 
in testing (documentation is sadly abit behind), mail me.

Dear Louis,

Did you managed to reach similar results?
I am also trying to reproduce the CVA in R, so I was wondering about it.

Thank you very much,
Best wishes,
M
