You entirely missed the point. We can never include every single relevant variable to perfectly explain the observation. It's impossible.
This doesn't mean statistics is useless.
This is the meaning of the phrase "the map is not the territory". All models are flawed, but some are useful.
- fwdpropaganda 9y agoI think there's some middle ground between saying that the analysis is rigorous and saying it's useless, no?
- dwaltrip 9y agoIndeed. But that's where all the hard work is -- trying to determine how rigorous something is, knowing it certainly isn't perfectly rigorous.
- mseebach 9y agoNo, statistics aren't useless, but its usefulness cuts both ways: if you can add one or two relevant variables and almost entirely remove the observation, then statistics tells you that the observation was only there due to omitted-variable bias.
- dwaltrip 9y agoSure, that's fine. That's part of using statistics to the best of our ability.
