Hello, I am a PhD student at the University of Adelaide. I am working on morphological data of a common species of marine kelp that I collected across Southern Australia (i.e. height, weight, surface area etc). I also have 5 environmental variables (latitude, longitude, exposure, depth and plant density) and I am wanting to do a canonical correlation analysis (CCA) to examine the overall ability of the suite of recorded environmental variables to explain the variation in morphological characters.
I have attempted a CCA in numerous programs (Statistica, SYSTAT and PC-ORD) but can not get all the information that I require from these programs (see query below). Whilst I would like to try the analysis on SPSS, this needs to be done on the MANOVA subprogram of SPSS. Firstly, is there anyone familiar with this program is it part of SPSS or do I need to access this as a separate program? Using the 3 programs mentioned above, I have been able to calculate the correlation coefficients for the morphological and environmental variables and yet can not calculate the variance explained (%) by each canonical axis (i.e. the proportion of the pattern common to the two data sets represented by each canonical axis). Secondly, whilst I can obtain the correlations between canonical axes and morphological and environmental variables (i.e. canonical factor loadings) as well as the variance explained by each axis (for both the Morphological and Environmental data sets), I can not calculate the cumulative variance of morphological characters explained by canonical variates of environmental variables (%) (i.e. what the % of the variation in the morphometric data set do the 5 environmental variables (collectively) explain). Both of these outputs are the main results I am after and I am unable to obtain them. Any advice on how to calculate these results or programs that include these results in the CCA output would be greatly appreciated!
