rpf.1dim.moment

spec

<p>data frame of item parameters, 1 per row</p>

params

scores

<p>Popular central moments include 2 (variance) and 4 (kurtosis).</p>

The purpose of this package is to factor out logic
and math common to Item Factor Analysis fitting, diagnostics, and
analysis. It is envisioned as core support code suitable for more
specialized IRT packages to build upon. Complete access to optimized C
functions are made available with R_RegisterCCallable().
