rpf.mean.info {rpf} | R Documentation

## Find the point where an item provides mean maximum information

### Description

This is a point estimate of the mean difficulty of items that do not offer easily interpretable parameters such as the Generalized PCM. Since the information curve may not be unimodal, this function integrates across the latent space.

### Usage

    rpf.mean.info(spec, param, grain = 0.1)

### Arguments

`spec` | list of item specs
`param` | list or matrix of item parameters
`grain` | the step size for numerical integration (optional)

### Details

WARNING: This function is experimental and may disappear.
