mLine 7:
Line 7: − === Experiment VS Observational studies === − Experimenting is to formally state spell out and control for as many variables as you can. Science. Because user makes sure to change nothing else during the experiment many issues with analyzing time based relations do no happen. Consequently linear regression, ttest, causal analysis and breakpoint detection work. Maybe some complications in establishing baseline. This needs a page combining (or two and not combining) experimental design and the techniques above. − − Second type is observational study. Just monitoring all the variables without a specific structure or interventions. This is what most health trackers do and is useful for many reasons. Also may remove placebo and stress or nervousness effect from a more formal experiment. Unfortunately this is where all those issues I mentioned in [[finding]] and many more in the links all are relevant. − − Maybe this comparison may need to be a page too.

For example "longevity[1][2], life expectancy, gerontology, life extension" some could be titles but each could be search term. [[User:DG|DG]] ([[User talk:DG|talk]]) 20:47, 10 March 2022
