Description
This function computes the reliability index, separation and the standard error of the models estimation.
Usage
checkRel(obj)
## S3 method for class 'seprel'
summary(object, ...)
Arguments
| obj | Object that resulted from any models estimation, e.g.,  | 
| object | The object of class  | 
| ... | Further arguments to be passed. | 
Details
Person reliability index
Value
A list of two objects, the reliability and the standard error.
reliability
- PRI Person reliability index. 
- PSR Person separation reliability. 
- IRI Item reliability index. 
- ISR Item separation reliability. 
stdError
- var_err_pers A matrix of variance error of the estimation. 
- std_err_pers A matrix of standard error of the estimation. 
- rmsse_pers Root mean square of the standard error per person. 
- var_err_item A matrix of variance error of the estimation. 
- std_err_item A matrix of standard error of the estimation. 
- rmsse_item Root mean square of the standard error per person. 
- hessian_theta Hessian matrix of - thetaparameter.
- hessian_beta Hessian matrix of - betaparameter.
