This is my first post in CrossValidated :)

I have the dependent variables: 1. Coughing when being fed liquid (Yes/No) 2. Coughing when being fed solid (Yes/No) and an independent variable: 1. Age group

I am thinking of using logistic regression method to answer the question "Is coughing related to age?". However, I am not sure how to accommodate both dependent variables in the model. I note the discussion here about multiple related outcome analysis but would like ask for your advice if it's relevant to my analysis.

Thanks in advance.

  • $\begingroup$ It looks like you have two dependent variables. Do you have both (liquid/solid) observations for the same individuals, or are the people being fed liquids and solids from separate sets? $\endgroup$ – david25272 Apr 29 '14 at 4:28
  • $\begingroup$ It's from the same individual. I have attempted to use both responses as separate incidence of the outcome (coughing) and run a logistic regression analysis adjusted for outcomes being sampled within group (individual) but not sure if it's the right way to go. $\endgroup$ – Kingsley Wong Apr 29 '14 at 7:00
