I have the basic understanding of the log-logistic (AFT) model estimates. If the
coefficient is greater than one the it reduces the survival time, and
increases survival time for values less than one. I am a little confused on
if I use a variable such as the log of income (ln(income)) in a level-log
format. Is it the same as regression (B/100)% change in beta. so, a one
percent change in income would equal a (B/100) change in survival? Thanks I
was search for days, but was unable to find the right answer.
