OK, in your hallmark #1, I suppose you're distinguishing between, say, topographic or land-cover maps that come from remote sensing and that might be useful in flood risk assessment, versus property-valuation or storm-drainage infrastr

I found the argument(s) interesting although the animations hurt readability and clarity. I've watched the area of commercialized remote sensing products with some interest, because I'm in the non-commercial remote sensing line.

Yes. In the simplified linear setting we're considering... If you want to do dimension reduction and only have X, use PCA. If you want to do dimension reduction and also have a "y", consider PLS or CCA (canonical correlation

Yes. And the consequences of the pre-1976 smog exemption are all too clear to anyone driving behind an older car on the freeway. There's no snow where I live, so these beautiful old heaps can stay on the road far longer than is healthy

Tuple, list, and numpy array are all different isinstance()’s, so I’d have to call them all out. len() avoids that.

There is no reason a priori to believe that integration and test of one of a kind space cryocoolers scales the same way postage does, or batching out parts at a drill press. I’d suggest that it’s on you to demonstrate why these analogies sh

The baseline take on what happened with Webb is that too many low-readiness technologies were included when the mission was approved and went into “Phase A” which means that development starts. The entire astrophysics community suffered as

Alas, I find this suggestion unpersuasive for the use I have in mind. I get that there would be cases it does apply to. I just want to enforce that the object acts like a list, mainly versus a float, int, or boolean. Tuples are definitely 1

I often use the same if len() construct. It will fail for non-list inputs, which is another reason it can be handy if you want clarify that you’re enforcing a list.

Exactly! The real decision you're making with scientific codes in lightly-explored problem domains is, how permanent and versatile of a solution do I need here? Alas, the OP is deploying some CS abstractions to genericize very simple p

The sample mean of a Normal RV does tend towards the population expected value, sure. The GP comment is talking about a Cauchy RV, which has heavy tails. So it has enough probability mass at large values that the expected value is infinite.

That's one effect. But in the western US, this effect turns out not to be the driver for hydrology. We've seen higher temperatures (causing more evapotranspiration), more highly-variable rainfall (thus, more precipitation lost to
