Abstract:
|
Increased emphasis on precision medicine has prompted the development of myriad statistical methods for both identifying moderators of treatment effect and estimating optimal rules for selecting treatment. Though many of these methods are promising, they do not perform equally well in all settings. Currently there is little guidance as to which method one should choose to use in practice. In this talk, we present results from a large simulation study in which we compare different recently-developed methods that simultaneously select important moderators and estimate treatment decision rules in a wide variety of realistic settings. The methods are compared with respect various performance metrics and guidelines for selecting methods to use in practice are proposed.
