WebJun 27, 2024 · Is it only ordered probit which are bounded by 0 and 1? This is because this model gives you in predicted probability of a given outcome. The most that can be is to go all the way from zero to one (or vice versa), so the change is bounded by -1 to 1. WebAn ordered response is a variable that is categorical and ordered, for instance, “poor”, “good”, and “excellent”, which might indicate a person’s current health status or the repair record of a car. In the absence of random effects, mixed-effects ordered probit regression reduces to ordered probit regression; see[R] oprobit. the outsiders johnny and dally relationship
