1 2	## S3 method for class 'iita' summary(object, ...)

`object`	a required object of class `iita`, obtained from a call to the function `iita`.
`...`	further arguments to be passed to or from other methods.

Summarizes the main results from inductive item tree analysis algorithms.

If the argument object is of required type, summary.iita returns the vector of diff values, the quasi order, the error rate, and the index in the selection set of the quasi order with minimum diff value.
