print.summary.din: Print Method for Objects of Class summary.din

Description

S3 method to print objects of the class summary.din.

Usage

## S3 method for class 'summary.din':
print(x, \dots)

Arguments

x

a required object of class summary.din, obtained from a call to the function summary.din (through generic function summary).

...

Optional parameters to be passed to or from other methods will be ignored.

Value

• If the argument x is of required type, print.summary.din prints the afore mentioned summary information in Details, and invisibly returns x.

Details

The print method prints the summary information about objects of the class din computed by summary.din, which are the diagnostic accuracies of the items, a summary of the corresponding skill pattern distribution and the model information criteria AIC and BIC. Specific summary information details such as individual items with their diagnostic accuracy can be accessed through assignment (see Examples).
