mleCalc

Description

returns the MLE for each case and asymptotic variance given a fixed set of item parameters. This is done by finding the root of the distance between the observed and expected score at theta. That is, the location where O-E = 0.

Usage

mleCalc(responses, itemParams, ...)

Arguments

responses	a data frame made up of rows of vectors of item responses, one for each case.
itemParams	a list of item designs (each used in a call to simplef). Must be of same length as responses.
...	optional arguments, e.g., perfAdj.

Value

a data frame.
