Good games for learning statistical thinking?

Are there any games that get the player "think like a statistician"? For example, lightbot gets you to "think like a programmer" (in a very basic way). Are there any games - designed for entertainment or teaching - that can help get one comfortable…

Real-life examples of common distributions

I am a grad student developing an interest for statistics. I like the material over-all, but I sometimes have a hard time thinking about applications to real life. Specifically, my question is about commonly used statistical distributions (normal -…

What are some interesting and well-written applied statistics papers?

What are some good papers describing applications of statistics that would be fun and informative to read? Just to be clear, I'm not really looking for papers describing new statistical methods (e.g., a paper on least angle regression), but rather…

Do you have recommendations for books to self-teach Applied Statistics at the graduate level?

I took several statistics courses in college but I found that my education was very theory driven. I was wondering if any of you had a text in Applied Statistics (at the graduate level) that you recommend or have had good experience with.

James-Stein shrinkage 'in the wild'?

I am taken by the idea of James-Stein shrinkage (i.e. that a nonlinear function of a single observation of a vector of possibly independent normals can be a better estimator of the means of the random variables, where 'better' is measured by squared…

Proper regression for determining correlations between derivatives of functions

Say we have a permanent-magnet DC motor that roughly obeys the system equation $\ddot{x}(t) = \alpha \dot{x}(t) + \beta u(t) + \gamma$ , where $x(t)$ is the displacement of the rotor, and $u(t)$ the applied voltage, at time $t$ . Say we wish to…

Good examples/books/resources to learn about applied machine learning (not just ML itself)

I've taken an ML course previously, but now that I am working with ML related projects at my job, I am struggling quite a bit to actually apply it. I'm sure the stuff I'm doing has been researched/dealt with before, but I can't find specific topics.…

Methodology for Reconciling "all models are wrong ..." with Pursuit of a "Truer" Model?

When attempting to model various phenomena, in practice, our model will usually be "wrong", but can still provide us with useful insights/predictions. What methodologies can we follow to help us balance the ability to create a useful/informative…

How Do You Choose The Number of Bins To Use For A Chi-Squared GOF Test?

I'm working on developing a physics lab about radioactive decay, and in analyzing sample data I've taken, I ran into a statistics issue that surprised me. It is well known that the number of decays per unit time by a radioactive source is Poisson…

Approximating the relative quantities of coins in Canada

Would it be possible to approximate accurately the relative quantities of Loonies , Twoonies , quarters, dimes, nickles (and perhaps the discontinued penny) in circulation from simply obtaining a large enough sample of coins through everyday use? By…
