Subject: Re: Shape analysis without removing size as a factor?
To: [email protected], [email protected]
Dear Celena,
whether that's appropriate for your specific
study, it might be a different matter. However,
there's a number of form spaces where size and
shape are analysed together. One of earliest
introduction I know on that topic is in Dryden &
Mardia, Statistical Shape Analysis. That's a great but quite 'technical' book.
The Viennese group has done a lot of work on
that. Goswami also, I seem to remember, had a
number of practical applications of analyses in a
form space (different from the one used by the Viennese people, I think).
An excellent introduction is Mitteroecker et al.,
2013, in the Yellow Book (link in my signature).
You'll find plenty more refs in that paper.
In terms of software, Morphologika easily allows
to get form data using at least two different
approaches to form spaces. You can then take the
variables from the CSV file with the results and
use them in other programs for more specific analyses.
Good luck.
Cheers
Andrea
