Papers by Brad Hanson

This page contains links to some papers on which I am an author. All papers are in Adobe Portable Document Format (PDF). Adobe Acrobat Reader (which is available for free) is needed to view the papers. The link for each paper points to a web page that provides a further description of the paper and from which a PDF version of the paper can be obtained. My vita contains a complete list of papers on which I am an author.

Notes

The following are short papers I have written that have not been presented or published elsewhere. Some of the papers do not present original ideas, but contain derivations of existing results that I wrote to help in my understanding of a topic.

• IRT Parameter Estimation using the EM Algorithm by Bradley A. Hanson

• Estimating Parametric Continuous Latent Distributions with the EM Algorithm by Bradley A. Hanson

• Extension of Lord-Wingersky Algorithm to Computing Test Score Distributions for Polytomous Items by Bradley A. Hanson

• Equipercentile Equating with Equal Interval Scores by Brad Hanson
