Ian,
This means you have more variables than specimens, which your data file
confirms. A parametric manova is not possible, because the algebra cannot
be completed, because the covariance matrix will be singular.

Hey everyone,
I am trying to run MANOVA on some morphometric data to determine if three
groups of specimens are statistically distinct. but i am receiving the
error code
Error in summary.manova(Raf.manova1) : residuals have rank 27 < 60.
Can anyone spot what i am doing wrong?
My data is
Dear all,
as an addendum to my previous message on tests for multivariate
normality, I've just noticed that a new R package for this (MVN by
Korkmaz et al 2014 -
http://journal.r-project.org/archive/2014-2/korkmaz-goksuluk-zararsiz.pdf ) is
out.
Best,
Carmelo

Dear morphometrics,
I have two questions about applying MANOVA on shape data:
1. MANOVA assumes the data to be normal distributed. What is the best
way to test normal distribution of multivariate shape data? And what
is the best (free) software for this issue (is this embedded in PAST)?
