    Relative Risk in logistic regression




    Hi all,
    I am very grateful to all those who write to me

    1) how i can obtain relative risk (risk ratio) in logistic regression in R.
    2) how to obtain the predicted risk for a certain individual using fitted regression model in R.

    Many thanks, in advance, for your help.
    Amin.

    You CANNOT get risk ratios from a logistic regression

    Guessing it is related to odds being calculated instead of incidences.

    You can't obtain relative risks but you can obtain odds ratios. See here; the odds ratios are the exponentiated coefficients and the predicted risk comes from the "predicted values"
