First off, I don’t have any experience with publishing based off the results of simulations. My (short) time in writing papers centered around economics research with observational datasets. I can tell you that given a fixed size dataset, i

If you’ve taken some statistics or econometrics, you’ve probably heard of “significance levels” and “p-values”. For some reason, academia choose 0.05 as a threshold for “meaningful” or “significant” results. Generally, a 0.05 p-value means

Of all the healthcare systems to negatively compare the US system to, I don't really think China is a good pick. Comparing the times that I've had to use medical care in China to my general experience in the US, I would opt for th

I think we have to be very clear on what economic "models" Goldman uses. If you're talking about GDP growth forecasting, or forecasting unemployment numbers, these are ultimately questions of aggregation. Yes, there are 7.5 b

Unclear if your comment is tongue in cheek, but assuming that you're serious, I'd encourage you to give a listen to a podcast episode like this: https://soundcloud.com/bettheprocess/episode-35-ted-knutson . In

Just to be clear, Microsoft tried to buy Yahoo for $45 billion in 2008, long before Marissa Mayer was CEO. As the parent comment notes, your previous comment seems to suggest some kind of causation between Mayer’s tenure as CEO and the even

You can't "subpoena" evidence, you subpoena live witnesses, or people to produce evidence. Since Brady v. Maryland (1963), prosecutors have to turn over any potentially favorable evidence to the defense. The defense can of co

It could certainly be that the German automakers are more concerned about present profitability. That could easily turn into falling victim to the classic innovator's dilemma. It seems that by year end, both the Model S and Model 3 wil

Wouldn’t you say this is a little glib? Nissan’s LEAF famously struggled with battery degradation over time. You can shade Tesla’s execution/financial performance/etc., but the battery technology improvements they’ve made are real

The loan that Theranos took out from Fortress last year is secured by the company’s assets and IP ( https://techcrunch.com/2017/12/23/theranos-gets-100-million-... ). Fortress is no slouch, but I wonder if thei

Not only did they endanger patient lives by using unready and flawed technology, they were brazen enough to lie about it in writing (in pitch decks) and on national TV (CBS This Morning and others). By putting blatantly false claims, like “

There is probably a cost consideration here. Every additional layer of supplier means more and more margin goes to them. I’d also imagine that if Tesla used the seat suppliers that the rest of the industry does, they’d get lower priority in

I think the differentiator vs. Tesla is that Theranos promised things that are/were physically impossible. Putting aside Tesla's long history of delays, I think it's fair to say that the company has delivered on some of its c

I think we may be talking past each other here. I just wanted to say in the previous comment that Theranos was already on the radar of the FDA and other regulators prior to the publication of that first article. Early complaints of Phoenix-

Fair enough! The book is worth the read. I think I may be being a bit unfair to the scientists. Basically, Theranos was a hot enough startup that Elizabeth Holmes and Sunny Balwani would fire, demote, or marginalize anyone who made a fuss.

The timeline/impact is a bit murkier. Carreyou had two big revelations. One was that Theranos was not running blood tests on their proprietary machines, which were supposed to do finger prick draws. The other was that Theranos had subm

The full process as described in the book is even more shocking. Theranos would dilute the finger stick draws, and then run them on the Siemens machines 5 times. In theory, you could then calculate the concentration, and adjust for the dilu

I agree there are a number of easy solutions in a mathematical sense. But the political battles around any of these paths are going to be intense. Raising the retirement age has been a non-starter because of the power of groups like AARP. A

Even if you’re choosing to ignore the actual study discussed in the article, which is worth a read, this is a logical fallacy. Most conservatives can be what we’ll call “non-seniors”, but most seniors can be conservative. These two statemen

It can certainly be the case that landmark Supreme Court decisions can dramatically alter the playbooks of prosecutors. For example, SCOTUS has in recent years tightened then widened the definition of insider trading. Gov. McDonnell got his

Ideologically, I’m inclined to agree with you. However, last year I read the book mentioned in the parent comment, The Chickenshit Club. One of the central arguments laid out in that book is that ultimately it is a “gentleman’s code” in the

I'm not claiming that it's one size fits all, but I think recommending a platform based off of revenue size is foolish. In my particular case, we maintain warehouses in 3 different states. Shopify does not offer a viable solution
