Generalization of cumulative probability models for ordinal Y

There are many models in existence for ordinal $Y$, for example the proportional odds ordinal logistic model, the continuation ratio model, and the cumulative probit model. The first and third of ...

Does the more complex model necessarily have a lower deviance?

I am aiming to compare the deviances of two models, an ordered probit and a multinomial probit, using the likelihood ratio test (obviously using the same data). However, I systematically obtain a ...

Ordered Probit Model in R: Latent Variable and Threshold Parameters

I have recently started to improve my methodological skills and programming in R. For a study term paper I now want to run an ordered logit/probit model. The data I use are taken from the European ...

Is it possible to have a lower AIC value for the smaller of two nested models?

I am testing the parallel lines assumption of an ordered probit model by running a likelihood-ratio test against a model where the coefficients can vary for each step of the ordinal response variable. ...

Model uniformly distributed response in cumulative link (logit/probit) model

I have an ordered response variable (stated preference from strong dislike to strong like) that is virtually uniformly distributed. I am using package ordinal in R to estimate the probability of an ...

Latent variable model where latent variable is in [0,1]

Suppose that my application's users are asked to give their opinion about the probability that a statement is true. They are presented with a slider widget that goes from 0% to 100%, but let's say the ...

Can Ordered Logistic Regression be used for tally/sum scores?

Suppose I have 6 vignettes and the possible responses to all those vignettes are 1 (YES) or 0 (NO). If participants answered (YES) to all six vignettes, they would get a tally score of 6. If they ...

Calculating predicted probabilities for ordered probit model

Trying to figure out how to obtain the values in the table below. For instance, for y=1, I did: 0.75-(-0.50)-15(0.052), and got 0.47. What am I missing? Please help!! Going nuts over this.

What regression diagnostics should I perform for an ordered probit?

Currently I have done the following diagnostics with the linktest multicollinearity with vif the parallel lines assumption with lr test of the oprobit and goprobit. I have seen that I may have to ...

What statistics can I use to compare OLS to an ordered probit

I am trying to justify to the use of an ordered probit, my dependent variable is a survey response on a likert scale so is likely ordinal, but I wanted to provide a goodness of fit stat to back up my ...

Testing if a correlation between two ordinal variables depends on a third variable

I have two ordinal variables : $y_1$ (a dummy) and $y_2$ (five categories). I know they are correlated, but I have reasons to believe this correlation depends on a third variable ($z$). An interaction ...

glm link functions for multinomial and ordered probit regression?

Here's what I understand, could someone please tell me if I'm wrong, and how? For a categorical variable $Y$, the expected value $\text{E}(Y)=\mu=\sum_{y}i\cdot\text{P}(Y=i)$. Using the descriptions ...

How to compare two non-linear models with different dependent variables?

I have two different dependent variables (Y1 and Y2). Both of them are ordered variables, but for Y1, it has 7 categories, while for Y2, it has 6 categories. Now, I am using probit model to analyze ...

Report coefficients or odds ratio in ordinal logit/probit?

I'm doing ordinal logit/probit only to analyse the direction of causality (e.g. if some variable makes it more likely to observe a low scale or a high scale). No interpretation is needed beyond this. ...
