pairwise (0.2.4)

Rasch Model Parameters by Pairwise Algorithm.

http://cran.r-project.org/web/packages/pairwise

The package pairwise offers functions for the explicit calculation -- not estimation! -- of the Rasch item parameters for dichotomous and polytomous item responses, using a pairwise comparison approach. Person parameters (WLE) are calculated according to Warm's weighted likelihood approach.
