Trying different imputation methods to find the most accurate may lead to overfitting the data, but it's probably balanced out by the more accurate imputation values. Hard to say. Train-Test splitting or Cross Validation can be used as well, but get computationally prohibitive. | |

Jun 29, 2022 at 13:52 | comment | added | jbowman | That's the "good" definition of "most favourable"; there's another definition - "gives me the best-looking study results" - that is akin to p-hacking. | |
Jun 29, 2022 at 11:07 | comment | added | olke | Thanks for such an elaborate answer! As a very fresh PhD student, I had no idea it may be considered shady. Could you please elaborate on why it's the case? I was under the impression that finding the most favourable imputation method (i.e. the one that yields the most accurate imputed values) is desirable (as opposed to p-hacking). | |
