is that asdf32 exists in one of our parallel universes, perhaps the one where Mike Judge's Idiocracy came to pass

The second is that the minimum wage should be abolished (since it's apparently impossible to determine what that should be without creating a country full of Geriatric Pirates, or Somalia), and everyone should be provided a minimum income indexed to cost of living in their area, subsidized through a 70% marginal tax rate on incomes exceeding $100,000 and an 80% tax rate on capital gains and high frequency trading while also removing the cap on contributions to social security. The cost of living would be determined through pricing a basket of goods in an area that includes a domicile that has one bedroom per person, internet access, public transport, cost of health insurance, provide for a minimum 2,500 calorie daily food intake and a $400 entertainment and miscellaneous expense allowance.

Are you serious? How many of the words in that paragraph do you think are jargon? Seriously, please list all of the jargon terms.

This is such a rich twist, in the previous post you accused me of having no real statistics knowledge, and now you accuse me of using too much statistics jargon because I whipped out a big word like "systematic", perhaps?

If there are unbiased fractional uncertainties, they're not going to be decreased by decreasing your sample size. Same for biased fractional uncertainties.

This is such an elementary point of statistics that I don't really know how else to drive this point home. You keep trying to claim that the smaller dataset has smaller fractional uncertainty, but it really, really doesn't. OLS is also being used by the other papers, and they had issues because the uncertainties were too large, so this paper should have at least the same issues! There are cases where this could be false, but you haven't given a good reason for why that would be the case. In your world it would be possible to drive down uncertainties by just randomly selecting a subset of data, but that is clearly not the case

You keep trying to use OLS as an excuse to ignore the large uncertainties, but surely you realize that OLS doesn't actually make those uncertainties go away, right? OLS can help drive down the final propagated uncertainty on your reported values, but those original uncertainties are still going to bite you in the rear end when you attempt to reject the null hypothesis, which is why this paper failed to do that.


It's a clever trap to lure idiots like you into revealing that they're illiterate

The R^2 is relevant, it's just not as important as the fact that the authors couldn't reject the null hypothesis. It's a supporting detail. The small R^2 supports the notion that the data has very large variance, which implies very large uncertainty. We know that both of these things are true, and the small R^2 helps to confirm it. It's like finding a bullet casing at the scene of a shooting; we already know that a gun was used, the casing is just a supporting detail (not like whatever dumb bullshit "sky is blue" thing you tried to use in a later post, god drat you suck at analogies)

You should try actually read the things that you're responding to before you respond to them.

Once again that's a whole lot of terms with no actual meaning behind them. Not sure what "fractional uncertainties" you're talking about but still not sure how you think essentially taking the mean and doing tests on it is better than using the actual raw data. Any problems you have in the data that affect ols coeffs affect the mean. This is really simple.

Still not sure how you think r2 which you now admit is irrelevant to testing a coefficient "helps confirm" anything. Does the sky being blue also help confirm that a murder happened?

Fractional uncertainty is uncertainty as, well, a fraction. Not knowing that it's kinda basic to literally everything involving statistics does a great job as outing you as an idiot.

Also the sky being blue confirms that the murder was on earth. You continue to be an idiot.

http://papers.ssrn.com/sol3/papers.cfm?abstract_id=630515 posted:

Much work has looked at the employment implications of raising the minimum wage, with a range of estimates reported in the literature. We offer new empirical evidence using output prices both at the store-level and aggregated to the city-level. In both cases, prices unambiguously increase in response to a minimum wage change. Furthermore, the results are similar across three sources of variation in the data: cross-state differences in the size of the minimum wage change, cross-restaurant type differences in the tendency to pay at or near the minimum wage, and cross-metro differences in the fraction of workers paid at or near the minimum wage. There is no evidence that prices fall in response to a minimum wage increase.
33
We interpret these findings within a simple yet quite general model of employment determination that shows that monopsony and perfect competition have opposite implications for not only employment but output prices as well, so long as the minimum wage is not set too high. In particular, under monopsony, an increase in a binding minimum wage causes employment to rise and output prices to fall. Under competition, employment falls and output prices rise. Therefore, our price results appear to provide evidence against the hypothesis that monopsony power is important for understanding the small observed employment response to minimum wage changes. Indeed, our estimated price responses provide evidence against other explanations of the small employment response, including the potential substitution of nonwage for wage compensation and the importance of endogenous work effort. Rather, we interpret our price results to be fairly consistent with the textbook model of labor demand.

Empirical data supports the Econ 101 model of the labor market? Of course an economist would say so.

Section 3.1 is totally useless as it assumes no errors in measurement. Section 3.2 is reliant on a statistical method that reveals high uncertainties in measurement, such that at best 20% of the variance can be explained, and at worst 2%. Section 3.3 shows that a quarter of the price movements are negative, and they are unable to explain this. Given that the price changes quoted are equivalent to 7% of the increase in costs, the data doesn't convincingly show what they claim it shows, as things stand.

I think he's the master troll though because he has a bunch of left wing posters here convinced that "fractional uncertainties" are a real concern. His logic basically says that let's say we have a clinical study on the effectiveness of a drug. Even though we can track who actually takes the drug and their health, we shouldn't do this because of fractional uncertainties. Instead, we should look at city-level averages for the use of the drug and health and measure those instead.

And of course use of the drug must explain at least 50% of variation in health, otherwise [insert whatever his incoherent argument about R2 here was] because we know that if Aspirin doesn't improve your life expectancy by 20 years, it's not really useful at all.

I don't know how they do things in the hellhole of suicidal ideation you live in, but in the United States of America, if you attended the sort of elementary science lab course that is included in general education requirements all around the country, and wrote in a lab report that you didn't need to account for or track errors and uncertainties, you would be marked down, and if the professor was a hardass, flunked.

Except that they don't reject the null hypothesis. Saying that you reject it is not the same as actually rejecting it. That kind of thing is okay for a working paper, which is what this is, but it's not acceptable to draw meaningful results from the paper in the meantime.
