   So glad that stringsAsFactors exists. Saves me a lot of time.

   Couldn't agree more. New users I help often get stuck when they run into factors. Skip the whole class! Strings are the way to go.

   There is not much here about deep learning or neural networks, but from a "how to measure and rate models" perspective, it is very helpful. I consider R to be a very useful skill-set. I have used it for solving many issues, both i

   Very helpful course, I highly recommend it. If nothing else, get a copy of the book: http://www-bcf.usc.edu/~gareth/ISL/ISLR%20Fourth%20Printing.... Even though the book is introductory material, it explains every

   Here is a link to the paper referenced in the beginning: http://courses.csail.mit.edu/18.337/2015/docs/50YearsDataSci... Great read for anyone interested in the debate.

   This sort of phenomenon can be seen lots of times throughout the past decades. Anytime oil falls below a certain price, it becomes cheaper to pay to keep the ships running offshore under the assumption that oil prices will increase in the n

   this is fun, but it gives you clues on where it will go next as the frame shifts before big movements.

   Exactly. I also wonder if the "canceled" orders are really just changing orders (either "cancel/replace" or "change" messages sent to the exchange) i.e. the desire to buy or sell is still there, just at a

    I agree, 36% ain't too bad. But,it requires that any literature you use in your research should have been reproduced a few times by other researchers.

    Agreed, amazing content but also a great tutorial for Julia. This is my first stab at it and it's great (as a daily R user).

    Do you think it's bleeding into other regional markets at all?

    There are also some refinery problems in Indiana which is keeping gasoline at a premium when compared to oil.

    There is a refinery problem in Indiana which is why gasoline is staying elevated even thought crude is falling. If anything happens along a refinement chain, there is a disconnect between market prices. The full affect is on the Chicago are

    Sure, investment in tech yes, but I would be very concerned about the massive increase in "space debris" in our lower orbits if things are getting blown apart. Enough war in space and we will need a clean-up method before people g

    All computer simulations are models, but not all models are computer simulations. What's taught in graduate school are text-book models which are descriptive at best. I am arguing that more thought should be given to trying to develop

    I mean computer simulation. Something that you can test many, many times that accurately reflects (or at least within reason) the affects of tweaking the parameters. I understand it's a difficult problem, but there has been some succes

    Not sure if there are any examples. Economists have never been very accurate because of the nature of economic systems. They are complex adaptive systems, which means that they are very sensitive to initial conditions. Because of the inhere

    We really need a way to simulate how the economy will react under certain policies. The current model is based on one hypothesis about how the economy works, when such policies may have been only tested once or twice before, AND when the te

    People who attempt data science without validating the statistics should eventually end up with a pretty bad track record and leave the "data scientist" job market. My perception of what data scientist currently means is a statis

    It's just a name. "Data science" still requires statistics and anyone who calls themselves a data scientist were (hopefully) trained in statistics at one point or another, whether formally or not. For those who don't use

    If you want to learn about data science, read this book: http://www-bcf.usc.edu/~gareth/ISL/ I have been going through it and I cannot think of a better resource.
