Software

ES Computer Program

The ES computer program is a user-friendly point-and-click program to compute (mostly) a d-statistic from a wide variety of kinds of input. The manual explains the overall functioning of the program and the algebra associated with each method. Copyright used to be owned by the University of Memphis, but in 2013 they approved returning ownership of the software to me. Users are encouraged to distribute the software and manual as they find useful.
