I have read many posts (including Frank Harrell's book) about the consequences of using variable selection strategies.
However, it seems that many of the published work in the medical field still follow step-wise, forward and backward selection methods.
variable selection using backward elimination cites Frank Harrell's book and have done a model selection based on AIC and then started interpreting the coefficients.
Is it meaningful to do in practice, in any sense? If they are not legitimate, why people keep using it and getting published in journals?
