Hi,
Is there a function to calculate probabilities for new out-of-sample data
once we fit a model using the in-sample data?
predict(model, newdata=... ) seems to require the new data to be the same
size as the original data used to fit the model.
It does not, so why do you assume so?
In short, I would like to fit a model and then pass out-of-sample data to
calculate probabilities.
That is what predict() is for.
Your subject line says 'polr model'. Perhaps this was about my package
MASS, but in any case please talk to the credit-where-credit-is-due
department.
And you could have seen this with a simple modification of the example
on the help page for MASS::polr ....
Regards,
Alp
