I am doing a study on tympanoplasty, a procedure to close one's eardrum. I would like to see if there is any correlation between a positive outcome (a.k.a. a closed typmanic membrane) and age. My outome is binary (open or closed tympanic membrane) and age is nominal. Is there a test that I can perform?

  • $\begingroup$ Hi, Elise. A fellow physician, here. So take it with a pinch of salt, but it sounds like you'd be happy with a binomial logistic regression, as pointed out below. Are you using [R]? What statistical package are you working with? $\endgroup$ – Antoni Parellada Aug 25 '15 at 16:24

You could run a binomial logistic regression. In matlab: http://nl.mathworks.com/help/stats/mnrfit.html
