A Testing if probability is the same for two groups

  1. May 31, 2017 #1
    Ok, so in a logistic regression context, I need to test if the probability of ##Y_{i}=1 ## is the same for two different groups at different ages where age is a continuous variable.

    This is actually complicated because of nonlinearity. Can I default to testing if the odds of ##Y_{i}=1 ## is the same for both groups?

    Or there is no one to one correspondence between the probability and odds?

    Can you state more clearly exactly what test you want to do? It is not clear from this description.
