  1. Re:So you want to retire a statistical term... on Why Standard Deviation Should Be Retired From Scientific Use · · Score: 2

    Gaussian distributions are a natural phenomenon, like pi, e, etc. The distribution was not made up for convenience (ever tried to integrate it?). You can't will away the base behavior of the universe (or our number line).

    Sampling any random variable which itself is a sample of smaller events will trend Gaussian by natural law. Noise is also often the sum of a huge number of random events, and is often quite Gaussian.

    Like binomial, Poisson, Laplacian, etc, Gaussians make a lot of sense for certain situations. Gaussian is also an excellent estimator for large sample sizes on binomial and Poisson processes.

    I don't really understand a general objection to Gaussian distributions, or their use in analysis. That would be like objecting to the use of the number e.

    Maybe you are upset that people assume Gaussians without considering it might be a similar distribution with very different process implications? (I.e. you can map a binomial on to a Gaussian, but the idea of where your samples are coming from is very different.)

  3. Re:Basic Statistics on Why Standard Deviation Should Be Retired From Scientific Use · · Score: 3, Interesting

    Didn't you hear? Guassians are so 1893. And so are all of the other distributions with convenient sigma terms...

    And TFS calls standard deviation "root mean square error", which is only true if you assume the mean is a constant estimator for the distribution :(

    In any case, no one picked Gaussians because they are so easy to integrate... While we're at it, TFA should suggest we round the number e to 3, because irrational numbers are hard, and who cares what natural law dictates.

  4. Re:In other words ... on Engineers: Traffic Studies Use Simulation Software, Not Lane Closings · · Score: 1

    I may be biased from a technocratic standpoint but here is a summary of the events as I understand them:

    * Agency 'A' is responsible for implementing policy 'P', which stipulates which applicants are to be awarded status 'S'.
    * 'A' has a database, 'D', containing the applications for 'S'.
    * Upon receipt of 'P', outstanding applications must be checked for compliance.
    * A set of database queries for 'D' are formed through non-algorithmic means (ie people came up with some terms they thought were common to political groups).
    * 'D' was queried and the results were held until further human review.

    I don't really see any issue here, unless your problem is with:
    * Bureaucracy in general - But there is no other way to run a large organization, given the shortcomings of human beings. That is really a totally separate debate.
    * The method of generating queries, which could easily have been biased. But requiring queries to be formed algorithmically would generate large cost overhead, as would a full re-review of all applications. Perhaps allowing Congress to review the queries before hand was a solution? That seems like a bit of micro-management.
    * The policy 'P'. But 'A' did not form 'P'. Blame the Supreme Court and Congress? Poorly defined laws lead to poorly implemented policies.

  5. Re:In other words ... on Engineers: Traffic Studies Use Simulation Software, Not Lane Closings · · Score: 2

    To be fair, the law states that the "primary purpose" of the group cannot be political, which is generally been interpreted as >50% of financial resources going to "non-political" action, whatever that means. It sounded like someone started doing database queries for words they thought were relevant for screening the database. Then someone else screamed that querying the database was unconstitutional.

    The quality of that comparison is rather like how a peanut compares to a car.

    There are a whole lot of peanuts out there. The complexity of products is growing swiftly, and engineering hours are reasonably well paid hours. Complete vertical integration is pretty much dead, so comparing any empire of the past to any consumer front-end today is disingenuous.

    As for whether or not overall worker pay is lower, nearly all free and competitive markets are a "race to the bottom" because consumers are rarely informed enough to purchase anything other than the least expensive (or most hyped) product. If this affects the job market. the consumers get the jobs they deserve. (Shit jobs for shit products and shit pay, because they wanted those shit products.)

    As for your house's strip heat coming on throughout the winter, blame your shithead developer/previous owner, and yourself for hunting a "bargain" at all costs.

    What horrors? (Actually asking. I have not heard of any.)

    My experience with the nVidia blob drivers has been entirely positive.
    I have had an equal or better experience with the nVidia Linux blob as I have with the Windows blob for ~8 years running. (Okay, I did have to run the installer from the command line way back when.)
    In fact, installing the driver is _easier_ on Mint (ergo all Debian-type systems?) than on Windows. Mint may have even come with an up-to-date driver already loaded.
    Optimus could be a problem. I don't use dedicated graphics for laptops any more.

    ATI, on the other hand, has given me nothing but nightmares. Both open source and blob drivers give terrible experience vs the Windows blob, and I still have issues with the package installs bricking my OS from time to time (pending recovery-mode driver uninstall).
