analysis Sender: [EMAIL PROTECTED] Precedence: bulk Hi everybody
I was wondering if anybody had some comments on the following dilemma. We are currently performing a tps analysis of body shape and possible left-right differences in a cichlid fish, and we have come across the following situation. It appears that relative warp 1 depicts a possible = artefact due to formalin fixation, which of course we would like to filter out. 1. We would like to know whether we can treat RW1 as you would treat PC1, depicting size, in a PCA, and thus immediately focus on RW2 plotted against RW3. 2. Could we consider RW1 as an independent variable in a statistical analysis, such as a MANCOVA, in which we would treat RW1 as a covariable and partial warps as variables? Would it be correct to perform this kind of analysis on the relative warp scores, taking into account that these scores are already the result of a statistic analysis, based on these partial warp scores? Can we somehow tease out the "effect" of RW1? Thanks in advance, Kristel Wautier Ghent University Department of Biology K.-L.
