“However, like with vitamin dosages and their effects on health, two variables might have a non-linear relationship.”
if we limit our interval we can make a linear approximation within that interval. this is often good enough if we don’t much care about data outside that interval. the easy pitfall of course is people wanting to extend the linearization beyond the bounds of the interval.
Voted down because tangential replies that belong elsewhere really get on my nerves. Please comment on the post about the vitamin study, linked in the OP.
