| May 16, 2018 at 20:57 | comment | added | gung - Reinstate Monica | @Denwid, there aren't typically references for not doing things under any circumstances (except for the most common & egregious--eg median splits). That said, there are a ton of papers that have shown problems w/ the common methods; you can see some listed here: Backward selection for Cox model using R. It should be obvious that for any method you would it use only when it would be both valid & help you achieve your goals. The point is that lots of people believe they should select features (& thus do so) when those criteria aren't met. | |
| May 16, 2018 at 20:34 | comment | added | Denwid | @gung can you point to some good sources arguin for not doing feature selection at all? | |
| May 16, 2018 at 16:41 | comment | added | gung - Reinstate Monica | Why do you need to select features at all? Feature selection has fewer benefits than people believe & a lot of potential pitfalls. | |
