I am an Industrial Hygienist, I have to carry out a silica risk assessment with the UNI EN 689 standard; I would like to have a copy of your BWstat3 program.
I look forward to hearing from you.
Best regards
The condition CVt = 0 was leading to a verification statement of 0 < 0, which caused an infinite loop.
The implemented safety measure would have broken this off after 2000 iterations of 10 000 Monte Carlo trials.
So, while it seemed to you that nothing was happening, BWStat was calculating frantically trying to improve precision.
Changing < to <= fixed the problem.
This special case of CVt = 0 also led to another programming issue, which I solved at the same time.
You can follow the details at https://github.com/remonds/Uncertainty-on-UTL/commit/b3778f6d509d2c2f859...
Is this solution satisfactory?
Thanks for your valuable reporting on this issue. BWStat is a program by and for occupational hygienists. Together we make it great.
Thank you for testing, Theo.
The dataset “Simulate data” gave, based on your input, is as designed. It seems you were expecting something different. Could you please describe what exactly?

BWStat is an online application
BWStat is an online application. It is free of charge for everyone. No copies are needed. It is accessible to everyone.

CVt=0
als CVt=0 dan gebeurt er bij mij niets in 3.1.0.
Klopt dat?
Voor CVt=0 kan de monte carlo worden overgeslagen
