| Aug 12, 2020 at 0:54 | comment | added | Dave | Then your outcome variable is how many deaths there are, not whether or not a subject lives or dies. What are you trying to model? | |

Poisson would be when the response is a count. Your response is a category that you happen to code as 0 and 1, but those numbers have no meaning. (You could flip which class corresponds time which number without changing much of anything.) | |

| Aug 12, 2020 at 0:39 | comment | added | user293790 | There’s a lot of alives and few dead. | |
| Aug 12, 2020 at 0:38 | comment | added | Dave | What is zero-inflated in this case, the response variable? | |
