Thanks for the link, to save anyone else the trouble, it seems that the rate for Bhutan is 89 out of 423 (21%) in country overstays. Average overstay rate for non visa waiver countries is 2.2%.

Okay, so I don't really understand what you're saying, but let me take a stab at it.

Somebody named GI Gurdjieff wrote a book "Meetings with Remarkable Men" in 1923, and in that book there was a kind of story in the introduction. That story attempted to distnguish between two different ways of life: a Western, "knowing" way and an Eastern "being" way.

The story basically involves a young sparrow eating cork which he thought was leftover thrown-out porridge and gets sick. Then an old sparrow says that in the old days, whenever a horse pooped you could always be sure to get undigested oats from it, but now when a car lets anything out, there is nothing to be had.

I guess the symbolism is that Gurdjieff was saying that the modern culture is deceptive in the sense that the "new" cork is not the same as the "old" porridge. So modern (Western) culture is poison, old (Eastern) culture provides sustenance.

And the connection to the posted article is that the "cork" is like the textbook definitions that Feynman described, while the "porridge" is like "true understanding/incorporation" of knowledge.

Is that what you were getting at?

I appreciate that others may not have got much out of this, but let me say that as someone who knows about statistical modeling, but has no physics training, this made Fourier transforms very clear.

There was another comment that referred to why we use this orthonormal basis versus another, and I think to appreciate the full reason of why this was done in the first place is important. But this presentation is a very good introduction for someone with my particular training.

In the full text, they did not appear to study the false positive and false negative rates. Their references to "sensitivity" were referring to the fact that they could detect even very small concentrations of the biomarker.

This is reasonable for this kind of study. I would expect a false negative / false positive rates in a study on the commercial device.

Thank you for providing this very helpful and needed context. I was indeed getting very excited.

The second point the grandparent made was that they were using dbplyr, which allows you to avoid having the data take a round trip between the R process and the database.

Okay, I'll bite. What is the string?

I also had these in my elementary school in Sault Ste. Marie. Mine were also used for games only, never programming.

I remember a game where you played the role of a colonial farmer in Canada and you got to decide what to plant every season. It always stuck with me because there was a bug that didn't allow you to skip one section.

I did miss it :). Thanks for letting me into the joke.

Was the MLK_ thing a joke? If not, could you provide a reference?

A good way to address your point would be to compare the situation to Canada.

In the province of Quebec, where we have a highly vaccinated population, the intensive care units (ICUs) in all hospitals will be full within two weeks, if the rate of transmission and hospitalization continue this way. Demand greatly outstrips supply.

In Canada, the financial incentives for hospitalization and discharge are very different. Physicians get paid by a complex mix of hourly pay in addition to a fee-for-service schedule, both paid by the government. Hospitals get paid by the type of patient they admit, and their length of stay, but not always in a straightforward way.

In Canada, because of the remuneration system, physicians are the most influential decision-makers in deciding who gets to use the ICU. Roughly, no one doesn't get admitted "because they can't pay", and no one gets admitted "because they have money" .

Since hospitals are overwhelmed in Quebec, physician's incentive would be to discharge patients rather than admit. Their hourly wage wouldn't rise if they got more patients. Indeed, there is some evidence that as ICU capacity drops, physicians start discharging patients from the ICU earlier.

I should be fair to physicians in Quebec: their behaviour reflects a deep concern about the public health emergency rather than their financial gain.

I believe that, in Canada, all hospitalized patients in the ICU really need to be there.

I laughed out loud (and was pleasantly surprised) when I found out how much you understated your expertise. I have only read a small bit of your dissertation, but so far it is informative and interesting.
