Accuracy of Estimating Two Parameter Logistic Latent Trait Parameters and Implications for Classroom Tests [electronic resource] / Michael J. Kolen and Douglas R. Whitney.

The application of latent trait theory to classroom tests necessitates the use of small sample sizes for parameter estimation. Computer generated data were used to assess the accuracy of estimation of the slope and location parameters in the two parameter logistic model with fixed abilities and vary...
