Review of DataWolff Bias Test Software

by C. H. Proctor

“I have run the software on examples provided. Even

for a novice with Excel like myself, the code works

easily. We first ran the ash-Btu example from Table

A2.12 of D6518 and I must say the graphics are a joy to

behold. The software is an undoubted success. It was

designed to allow practioners to run Hotelling’s T2.

Mr. Hotelling would be proud.”
