iid

Supposing iid shocks hit all industries; then over time, even if prices haven't changed, underlying conditions have ... and industries are all closer, or farther, from some threshold beyong which they will go ahead and adjust prices upwards.

They say they have many different measurements and they are all iid.

Basically, a Pearson correlation coefficient is frequency-independent, and is thus a poor measure of ‘match’ between two non-iid process.

Weather records at a number of stations in the US were examined and in each case were indistinguishable from white noise or an iid process.

The post you linked to is certainly amusing, but the argument assumes that whatever errors are iid across time and place.

But, when you look at them in detail, not only are the measurements not all measuring the same variable i.e. many are proxies, but even the direct temperature measurements turn out not to be so iid.

Neither means squat if the iid assumption is violated.

Another way to put this: changes in temperature anomolies are larger than expected under iid, have no significant drift, and have strong reversion.
