11.7 An example: estimating parameters

Now let us fit the DINA model to the data and estimate attribute profiles using three different approaches:

Code

library(GDINA)
est <- GDINA(Y, Q15, model = "DINA", verbose = 0)
MLE <- personparm(est, what = "MLE")
MAP <- personparm(est, what = "MAP")
EAP <- personparm(est, what = "EAP")
