Is it possible to use any kind of phylogenetically informed analysis in case of multiple regression (one response ~ multiple predictors) in case I assume binomial distribution of response variable? I try to explain species occurrence (proportional data) by species traits.
I tried pgls function from "caper" R package, but I am not sure about it.
Hi Jana,
If your response variable is binary, I would recommend trying logistic regression. Logistic regression measures the relationship between the categorical dependent variable (yes/no, winged/wingless, large/small, present/absent, etc.) and one or more independent variable, similar to multiple regression, using a cumulative logistic distribution.
If you're using R, there is a decent walkthrough with detailed explanation of logistic regression in R found here: http://www.ats.ucla.edu/stat/r/dae/logit.htm
Best,
Aaron
