    Once there are actual policy changes due to Brexit. Right now the pro-leave campaigners are riding on short public attention-spans, but the UK has a slightly more sophisticated democracy that is resilient to sabotage, and will most likely right the ship by destroying May and the conservatives, and reversing course to remain in the EU.

    Markets are often delusional. Tesla has yet to turn a profit, claiming growth - yet every other firm manages to grow while it is profitable. Tesla has significant governance issues, so it isn't being managed well at all.

    Unless Tesla doesn't have any coherent thought of their real future. Then anything could happen, and unfortunately that bears more from fact than your theory does. See their poor returns, poor investment policy, shoddy factory management, etc.

    The raw number of victories on any issues is the significant measure of effectiveness. Cost per petition is tiny, and diversity increases impact as well as traffic and exposure for all petitions. Global scope means it isn't tied up in the American political gang wars. For instance, The fight against slavery in Mauritania benefits from exposure to those in nations that enforce peace and human rights. Those who could end it don't because they think it doesn't hurt them, but a sign of international will scares them into action. Force always follows awareness, and that applies all the way from economic to military intervention.

  7. Read that report again - 25% of total expected costs is not the same as 25% of revenue or profit, and that figure isn't the operating margin. That report does show benefits from increased megawatt designs, and shows how even the estimate on maintenance cost is of limited use in future forecasts. Notice the cost graph is from 2002 showing units then 3-15 years old; that means the sample is made from units made between 1987 and 1999. Technology has evolved rapidly and even units from before 2012 are barely comparable.

    30% of revenue from energy production is equal to maintenance costs? Over what period, unit lifetime? In what environment? Regardless, to determine value you must compare whatever failure rates to energy produced in best, worst, and most frequent conditions. You can approximate the beta distribution with the triangular distribution and with reliability engineering you can find expected time until a repair event. Then you can figure out how likely each individual unit is to break even, and beyond that to produce profit. Those are the metrics of greatest interest, and given that market trade is the mantra of modern China that is the only motive required. All others face the test of reality vs paranoia.

  9. Re:Huh? on Chinese Company Offers Free Training For US Coal Miners To Become Wind Farmers (qz.com) · · Score: 3, Informative

    I recall retraining was Clinton's solution to this specific skill gap problem, so Trump will hate it and do all that is possible to sabotage it. Effective training (free for the unemployed minimizes adoption costs) does a better job of putting unemployed coal miners back to work than Trump's practice of subsidizing industry with bribes. This will face even more opposition because now the Chinese are the ones showing that his poorly conceived approach doesn't work, but the only ones who will take damage from sabotage are the currently unemployed coal miners.

    Basically it is a new name for statistics done by computer scientists who don't understand sampling or any theory for the models they are applying. That means most real requirements of those models aren't addressed unless a statistician later looks over their work. There are some add-ons however, and things like cross-validation while logical extensions of the underlying models are typically done with computational tools. The focus is typically on web scrapping with poor consideration for the types of errors that exist, and a large part of faith based belief in a fake census style approach to obtaining meaning from whatever data is gathered.

  11. This is the perfect tomato for human health. This research extends to tomatoes the same concept Norman Borlaug used to optimize the production of wheat and rice in the 60s. You know, the Green Revolution that legitimately kept the world from starving itself to death and decreased warfare. There are major health benefits from consuming tomatoes in any form, and this research increases production and descreases costs in a way that will increase tomato availability.

  12. Not quite as seasonal variation itself is really the sum of several factors that themselves are influenced by longer cyclical patterns. Think y=5*t(n-1)+t(n-1)+5*t(n-1)*t(n-60) or something similar. The difference of a single year n-12 won't influence that, and the operation itself can't deal with multiplicative terms.

  13. No, year over year differences only remove the linear trend, the y=t(n-1)+error part, not the seasonal multiplicative y=x*t(n-1) parts. For example if summer travel is best estimated as y=5*t(n-1)+t(n-1)+error, such that differencing leaves y=5*t(n-1)+error (since error isn't a constant). Where t(n)=travel in month n, and t(n-1) is the same value in the previous month.

  14. Causation can be demonstrated on US International Tourism Market Share Is Falling Under Trump (buzzfeed.com) · · Score: 1

    It is possible to show specific events are important but that requires some specialized knowledge to understand. Plainly, you can do it using piecewise regression. There is significant autocorrelation since this is a time series, and as another post mentioned the mentioned seasonal effects are not disclosed here. They are however available if someone is interested enough in research. In this case my point is limited to modeling. Given a dummy variable keyed to the US election duration and conclusion it would actually be possible to determine the impact of particular events in time based on significant changes in the regression parameter estimates. See here for the general idea.

    You are denying the economics that exists in favor of a baseless fantasy. Natural gas made coal unprofitable, and the only debatable "outside" force is the reality of responsibility for the externalities previously socialized out to the mining communities. Those costs must be made whole by the firms operating the mines as they caused the air and water pollution killing their own workers.
