Methods for extended Rasch models

Description

Usage

## S3 method for class 'eRm':
print(x, ...)
## S3 method for class 'eRm':
summary(object, labels = TRUE, ...)
## S3 method for class 'eRm':
coef(object, ...)
## S3 method for class 'eRm':
model.matrix(object, ...)
## S3 method for class 'eRm':
vcov(object, ...)
## S3 method for class 'eRm':
logLik(object, ...)

Arguments

x Object of class eRm.
object Object of class eRm.
labels If TRUE, items are labeled.
... Further arguments to be passed to or from other methods. They are ignored in this function.

Details

vcov returns the variance-covariance matrix of the parameter estimates, coef the estimates of the basic parameters, print the value of the log-likelihood and the parameter estimates and their standard errors, model.matrix the design matrix, logLik the log-likelihood value.
