I have a gene expression dataset that I want to investigate. Particularly, I would like to understand whether there is any correlation between each gene's expression and some quantitative or qualtitative data (say, correlation between gene 'XPTO' , body mass index, and race).
One possible way to test this would be through logistic regression, but is this a good approach or are there caveats that I should know about using such a statistic?
My question is the following: which methods would you advise to measure such correlations, and why?
