I am currently working with some survey data that has a 5 category scale. I have used a ML method before for a 4 category scale and I am trying to adapt the code for the new survey in R.
The original code that worked was:
#Load Data
mathcomp <- read.csv("RRawComposite11.csv"...
Hi all,
Does anyone know if it is OK to use an ordered probit model to predict a latent variable, e.g. self-perceived health; and then use the linear predictions as a right-hand side variable in another ordered probit to predict a different latent variable, e.g. life satisfaction. The...
hi
Anyone knows how to perform a test for heteroscedasticity in a ordered probit model in R?
I tried to use bptest(model) and I tried plot(model, which=1), but these comands only seem to work for linear models..!
Kind Regards

Hello there
If I want to estimate an ordered probit mode,l because my depend varible takes the ordered values 1,2,3 and 4, can I do that if I only have discret explanatory variables?
Kind regards

Hello. I'm trying to fit a multivariate, unrestricted cumulative probit model. I've had success in fitting a proportional odds probit model using polr(method="probit") in the MASS package and the unrestricted cumulative probit model using vglm(cumulative(link="probit)) in the VGAM package...
I want to run a regression: (person's stock performance rating) = B(nonS&P/S&P500 portfolio concentration) + Ei
...where a person's stock performance is on a 1-10 point scale.
I want to see what the probability a person's rating will be given the concentration of nonS&P to S&P stocks.
