Probability and statistics blog. In Monte Carlo We Trust. The surprisingly weak case for global warming. I welcome your thoughts on this post, but please read through to the end before commenting. Also, you’ll find the related code (in R) at the end. For those new to this blog, you may be taken aback (though hopefully not bored or shocked! TL;DR (simple version): Statistician does a test, fails to find evidence of global warming. The earth has been getting warmer. This warming is part of a long term (sec...

I know, it’s really bad. But let’s get on to the good stuff, or, perhaps more accurately, the really frightening stuff. The plot shown at the top of this post is a simulation of the martingale betting strategy. You’ll find code for it here. What is the martingale betting strategy? Pretty scary, no?

Probability and statistics blog. In Monte Carlo We Trust. Mdash; 9 Comments. Uncovering the Unreliable Friend Distribution. Head down to your local hardware store and pick up a smoke detector. Pop off the cover and look inside. You’ll see a label that mentions Americium 241, a radioactive isotope. Put on your HEV suit. Just how long will you have to wait? And created an exponential timer you can try out for yourself. I would suggest setting it to less than 432 years. Cranking uncertainty up to 11. The lo...

Probability and statistics blog. In Monte Carlo We Trust. What’s my daughter listening to? HTML chart gen in R. My daughter, who turns 10 in April, has discovered pop music. She’s been listing to Virgin Radio 99.9. One of our local stations. Virgin provides an online playlist. That goes back four days, so I scraped the data and brought it into R. The chart shown at top shows all of the songs played from February 17th through the 20th, listed by frequency. Anyone want to give it a try? Here’s my code.

Olivier H. Beauchesne. Chart Miner – Exploring 2d Projections. March 30, 2016 2:23 am. Olivier H. Beauchesne. T-SNE, PCA and other dimensionality reduction algorithms have always been a good way to visualize high-dimensionality datasets. Unfortunately, most of the time, the visualization stops there. If another view of the data is needed, a new chart needs to be computed, projected and displayed. 15 Years of News Analyzing CNN Transcripts: Visualizing Topics. March 24, 2016 10:52 am. When we extracted th...

Probability and statistics blog. In Monte Carlo We Trust. Mdash; 12 Comments. Review of Mathematica 9 and R-link. Before I begin I’d like to thank Jeff Hara and Andy Ross from Wolfram for their time. Also thanks to the folks at the Mathematica Stack Exchange. Who helped with a couple of my questions. After each line I’m hitting Shift Enter to run the command, if you just hit enter Mathematica won’t run things yet. So I’ve cleared my variables and I’m going to run. Note that the free version of Mathematic...

Probability and statistics blog. In Monte Carlo We Trust. Knowledge that is with us at the very beginning, based on previous observations or experience. Our initial assumptions are. A number so big you can’t understand it. An experiment performed by generating lots of randomly sampled numbers. Monte Carlo methods can be extremely powerful and are able to simulate processes so convoluted that finding a mathematical equations to describe them would bring a room full of Erdős 2.
