A revised version of the MiscPsycho package has been uploaded to CRAN. The fixes include:

  1. A bug found in the class.acc() function that resulted in overflow errors when computing probabilities associated with polytomously scored items has been resolved. The function now integrates over the posterior distribution of an IRT model for dichotomously scored items, polytomously scored items, or a combination of the two.
  2. The help page for the irt.ability() function was updated. There was previously an error indicating that the function used the argument 'std.error' when the argument should be 'std.err' in order to get the standard error on the IRT ability estimate.

Any other comments, bug reports, or suggestions are welcome.
