A correlation is good enough for me.Correlation does not necessary mean
causation,but it sure indicates an influence.
What else do you need?Let us not forget interaction.
The good thing about correlation is that it may assume a multiplicity of
factors whereas causation is restrictive.
This is wrong in so many ways I can hardly begin to specify them. As
long as I can deter anyone else from being influenced by this set of
spurious claims, I'll be satisfied.
Regards,
I'm right in the middle of correlation research and I am always careful
to assert that (in this case) high fructose corn syrup is highly
associated with an increase in body fat. I never say "causes" unless
there is a tightly controlled, large enough EXPERIMENT (14 men and 44
men is not large) to indicate this is likely the case (see even then I
use the tentative language).
