Computer Programs to Compute Lord's Item Bias Statistic for a Three-Parameter ICC.
Downey, Ronald G.; Stockdale, Margaret S.
Educational and Psychological Measurement, v47 n3 p637-41 Fall 1987
Lord's method for detecting subgroup bias at the item level uses a three-parameter item characteristic curve model. A chi square statistic is computed on the multivariate differences between the parameter estimates of item discrimination and difficulty. The LOGIST program and additional programs written in BASIC are used. (Author/GDC)
