Function to calculate various person attribute parameters, including "EAP", "MAP", and "MLE", for EAP, MAP and MLE estimates of attribute patterns (see Huebner & Wang, 2011), "mp" for marginal mastery probabilities, and "HO" for higher-order ability estimates if a higher-order model is fitted. See GDINA for examples.

personparm(object, what = c("EAP", "MAP", "MLE", "mp", "HO"),
  digits = 4, ...)

Arguments

object

estimated GDINA object returned from GDINA

what

what to extract; It can be "EAP", "MAP", and "MLE", for EAP, MAP and MLE estimates of attribute patterns, and "mp" for marginal mastery probabilities, and "HO" for higher-order ability estimates if a higher-order model is fitted.

digits

number of decimal places.

if (FALSE) { dat <- sim10GDINA$simdat Q <- sim10GDINA$simQ fit <- GDINA(dat = dat, Q = Q, model = "GDINA") # EAP head(personparm(fit)) # MAP head(personparm(fit, what = "MAP")) }
