Separate health issues?
As I can see that the opposition on this issue has nothing left than a willingness to revert solid evidence without comment and resort to ad hominem attacks, I have asked Philippe Beaudette, who claims that he has "not insignificant" experience with survey design, to a public debate on this topic.[1]
I am closely familiar with the applied statistical mathematics inherent in survey design, and the peer reviewed secondary medical literature on the topic and I look forward to seeing them upheld.
All i can understand is that You want a custom tailored survey to "support" your point.
I may be wrong but that how i read your argumentation. A slanted survey giving biased results to support The already made conclusion.
If the conclusion were already made, then a survey would not be necessary.
However, excluding an independent variable implies that variable is not any part of the mutual hypotheses.
Nope.
That's always good to fabricate self justification & evidences to support already made conclusions.
What are you saying has been fabricated? Do you have any actual evidence supporting your one-word dismissal of the mathematical facts I stated? They are evident from first principles.
