Dr. Charles Zaiontz has a PhD in mathematics from Purdue University and has taught as an Assistant Professor at the University of South Florida as well as at Cattolica University (Milan and Piacenza) and St. Xavier College (Milan).
Most recently he was Chief Operating Officer and Head of Research at CREATE-NET, a telecommunications research institute in Trento, Italy. He also worked for many years at Bolt Beranek and Newman (BBN), one of the most prestigious research institutes in the US, and is widely credited with implementing the Arpanet and playing a leading role in creating the Internet.
Dr. Zaiontz has held a number of executive management and sales management positions, including President, Genuity Europe, responsible for the European operation of one of the largest global Internet providers and a spinoff from Verizon, with operations in 10 European countries and 1,000 employees.
He grew up in New York City and has lived in Indiana, Florida, Oregon, and finally Boston, before moving to Europe 36 years ago where he has lived in London, England and in northern Italy.
He is married to Prof. Caterina Zaiontz, a clinical psychologist and pet therapist who is an Italian national. In fact, it was his wife who was the inspiration for this website on statistics. A few years ago she was working on a research project and used SPSS to perform the statistical analysis. Dr. Zaiontz decided that he could perform the same analyses using Excel. To accomplish this, however, required that he had to create a number of Excel programs using VBA, which eventually became the Real Statistics Resource Pack that is used in this website.
I cannot find any articles by Charles Zaiontz, so I am unable to cite his work. It would be important to be able to do so.
José,
Here are some of the articles that I have published
Deterministic Automata and the Monadic Theory of Ordinals < omega2 Mathematical Logic Quarterly, 1983 Axiomatization of the Monadic Theory of Ordinals < omega2 Mathematical Logic Quarterly, 1983 Randomized controlled study on the effectiveness of animal-assisted therapy on depression, anxiety, and illness perception in institutionalized elderly Psychogeriatrics, Sep 16, 2018 Capacity Management for SNA Networks - A Management Perspective Int.

Dear Charles,
I apologize for my delayed acknowledgment of your suggestion regarding my problem. My problem was resolved after reinstalling the resource pack. Thanks and regards!
Dear Charles,
I am looking for comaprison of two results obtained with two methods from identical data – using RealStat I have calculated 95% propability of postitive results (so called LoD value, using logistic regression). Than I applied slightly modified method and got new result from recalculated data. From three such measurement I got mean LoD value and SD value (LoD 129 +- 33 SD old method vs LoD 131 +- 6SD recualculated). Now, I should use statistic to confirm whether values are identical and do not differ – what method should I use?
Thank you a lot for helping. Your RealStat is an excellent too I love to utlize it as Excell Add-In.
Kind regard,
Edita
Hello Edita,
Glad to learn that RealStat is helpful to you.
There are various methods for comparing one method with a newer method (usually one that is less expensive to implement or has some other advantages) to see whether the results are compatible. These are described on the Real Statistics website and include
Bland Altman
Lin’s CCC
Deming Regression
