Methods for shape analysis of landmark data from articulated structures. Evol. Ecol. Res. 1, 959-970 I've done a few things with analyses of separate views of the same structure. If you want, you can get in touch directly with me and maybe have a quick chat on Skype (next week, probably). Cheers Andrea At 16:30 29/12/2008 -0500, you wrote:
-------- Original Message -------- Subject: MANOVA with 2 views for each specimen ? Date: Mon, 29 Dec 2008 13:14:54 -0800 (PST) From: jay carroll <[email protected]> To: [email protected] Hello all. I have a data set which comprise two views (dorsal and a lateral) for each individual. Both views have been digitized and partial warps&uniform components have been generated. I have performed a partial least square analysis to investigate the covariation between the two views. But my question is focused on the differences between different ecological groups. My first inclination would be to perform a MANOVA model. But would it be more appropriate to analyze this data with two separate MANOVA models (dorsal and lateral)? Alternatively, could both the dorsal and lateral partial warps and uniform components be distilled down to a few principle components and analyzed in a single MANOVA model? Is this approach off base? Any special considerations since both dorsal and lateral views are composed of two separate shape spaces? Any comments on this idea or relevant citations would be appreciated.
