# Detrended correspondence analysis

I have relative abundance data of monkey species in 4 different types of habitat. I would like to use detrended correspondence analysis. Is this a correct way to display my data? If so, how should I enter the data?

• Seem like a reasonable plan. Worry about the detrended after you've got the basic correspondence analysis going. But what do you want to 'enter the data' into? – conjugateprior Aug 11 '15 at 0:58
• Can you add more information here, Carla? I don't know if this question is answerable at present. – gung Aug 11 '15 at 1:04
• @gung I'm aware of what it is - it's a somewhat old school version of CA that tries to undo the arch effect. In the vegan package it's called decorana, I believe after the old software that made it popular. – conjugateprior Aug 11 '15 at 1:10
• My hope was that we would learn what the data was going into. If it were R I would recommend looking at the vegan documentation. If into SPSS I wouldn't be so sure what to recommend (if you can even do it there). – conjugateprior Aug 11 '15 at 1:11
• @gung not a problem – conjugateprior Aug 11 '15 at 1:12
