I’m doing background research on the origin of “Walsh” averages. It’s referenced in the Wilcoxon nonparametric hypothesis testing in Minitab statistical software. I understand the use of the stats, but want to know more about “Walsh”. 1) who was Walsh?? First name? .. Full name?? 2) timeframe for “Walsh” averages .. when? 3) where was the work done? .. city, country?? 4) Academic or industry application?? Which university or company??

Appreciate any assistance. Thanks.
