| Dec 2, 2020 at 22:53 | comment | added | Demetri Pananos | The problem exists in the estimation of the effect. The significance doesn't really matter all that much. You're free to try and demonstrate that the cut off threshold of p=0.25 leads to the type of behaviour you expect, but I'm rather confident it will not. | |

| Dec 2, 2020 at 22:50 | comment | added | Rodrigo_BC | They use: "bivariable analysis is greater than an arbitrary value (often p = 0.05)"... I use p-value= 0.25 in bivariable analysis... I know that stepwise have a lot of critics but main interest is in bivariate regression... | |
| Dec 2, 2020 at 22:47 | comment | added | Demetri Pananos | You're still subject to the criticisms in those papers. Enough evidence exists that these methods do not accomplish what users think they do. Use them at your own peril. | |
| Dec 2, 2020 at 22:46 | comment | added | Rodrigo_BC | Only I use manual stepwise and main effects model. Thanks for papers... | |

| Dec 2, 2020 at 22:43 | comment | added | Demetri Pananos | I would not do this. Pre-filtering fails to account for confounding variables, and so your selection method could miss important effects. See this paper for more pubmed.ncbi.nlm.nih.gov/8699212. Finally, stepwise is a method fraught with faults. See Frank Harrell's problems with stepwise regression or these artilces journalofbigdata.springeropen.com/articles/10.1186/… | |
