TexaSoft Program Validation Information

Program Validation

The core statistical procedures in the KWIKSTAT programs (including WINKS, the Windows version of KWIKSTAT) have been developed and used for more than 15 years. Every revision of the program during that time has been tested in-house against the results of other major statistical programs such as SAS, BMDP, and SPSS. In addition, over 50 outside testers from universities, government and corporations world-wide periodically participate in further and continuous testing of the programs. If errors are found, the procedure is updated and re-tested, and corrected versions are sent to every user who is registered with TexaSoft program support.

Published benchmark data sets, standard reviews of statistical procedures, and standard textbooks are also used to test statistical procedures. Below is a list of some of the papers and texts used to test program procedures and results:
