LINEQUATE: Stata module to calculate linear equating constants using the Tucker and Levine Methods
Abstractlinequate computes equating constants to perform linear equating of two versions of a test using an anchor test. The methods for computing these equating constants include Tucker's method, Levine's equal reliability method, and Levineís unequal reliability method. Users can easily obtain the equating constants by importing scores from the anchor test, and two different versions of the test. The equating constants can then be used to transform the scores from one version of the test to the scale of the other version of the test.
