Extracts expected counts for models fitted in TAM. See CDM::IRT.expectedCounts for more details.

# S3 method for tam
IRT.expectedCounts(object, ...)

# S3 method for tam.mml
IRT.expectedCounts(object, ...)

# S3 method for tam.mml.3pl
IRT.expectedCounts(object, ...)

# S3 method for tamaan
IRT.expectedCounts(object, ...)

# S3 method for tam.np
IRT.expectedCounts(object, ...)

Arguments

object	Object of class tam, tam.mml, tam.mml.3pl, tam.np or tamaan.
...	Further arguments to be passed

Value
