Description: STDIF os a DOS-based program to compute DIF indices of conditional p-value differences between two groups of interest: the reference group and the focal group. This is a large-sample procedure requiring a minimum sample size of 10 people in each group at each score point, and was designed to be used with state level data, not pilot samples where sample sizes are typically smaller.
