Subject: Ability estimates for partial credit model
Dear all,
I'm working on ability estimates using Rasch model. Using the "ltm"
package, the procedure is quite simple:
## Factor Scores for the Rasch model
fit <- rasch(LSAT)
factor.scores(fit)
What about Partial Credit Model (PCM)? For PCM I use PCM function from
eRm package. Is there any similar function like factor.scores to
estimate ability scores using PCM model?
Best, Andrej
