It's not by chance.
If you have a heater controlled by a thermostat, it destroys the correlation that would otherwise exist between outside temperature and inside temperature.
That particular example sounds silly because it is so obvious. But in economics you can find examples where you would be seeing a relationship, but it is masked by an active response to the cause, but it's not so obvious this is happening.
- Symmetry 4y agoThat's the thing though. A heater controlled by a thermostat will considerably reduce the correlation between outside and inside temperature but because it's imperfect it wont' eliminate it entirely.
