print(x, ...)
## S3 method for class 'eRm':
summary(object, ...)
## S3 method for class 'eRm':
coef(object, ...)
## S3 method for class 'eRm':

vcov(object, ...)
## S3 method for class 'eRm':
logLik(object, ...)
## S3 method for class 'eRm':
confint(object, parm, level = 0.95, ...)

Arguments

x

Object of class eRm.

object

Object of class eRm.

parm

Either "eta" or "beta".

level

Alpha-level.

...

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.

Examples

data(raschdat1)
res <- RM(raschdat1)
print(res)
summary(res)
coef(res)
vcov(res)
model.matrix(res)
