| Jan 14, 2023 at 4:00 | comment | added | BioinformaticsB | @utobi thank you for querying. If first level of 'factor' is a control condition for example, doesn't inspecting the interaction between categorical and continuous in the control allow one to see the potential relationship (confounding) present between predictors and outcome prior to intervention i.e. intervention being the successive levels of factor? | |
| Jan 13, 2023 at 11:59 | comment | added | whuber♦ | Create an indicator of the first level of the factor and interact that--and only that--with the continuous variable. Subsetting is not the same. | |
| Jan 13, 2023 at 8:04 | comment | added | utobi | I don't find interaction of categorical and continuous under only the 1st level of 'factor' meaningful. Can you explain what are you aiming at? It it's only a matter of coding this question would be off-topic here. | |
