I've blogged about The Econometric Game previously - see here, here, and here.It's April, so the Game is on again - today and the next two days, to be specific. You can check out he details, as they become available, at this site.Good luck to all...

According to the central limit theorem, if random variables, , are independent and identically distributed, is sufficiently large, then the distribution of their sample mean, , is approximately normal, and this approximation is better as increases. One of the most remarkable aspects of the central limit theorem (CLT) is its validity for any parent distribution of […]

-+*Cancer research is sometimes criticized for being timid. Drug companies run enormous trials looking for small improvements. Critics say they should run smaller trials and more of them. Which side is correct depends on what’s out there waiting to be discovered, which of course we don’t know. We can only guess. Timid research is rational […]

This would make Karl Popper cry. And, at the very end: The present results indicate that under certain, theoretically predictable circumstances, female ovulation—long assumed to be hidden—is in fact associated with a distinct, objectively observable behavioral display. This statement is correct—if you interpret the word “predictable” to mean “predictable after looking at your data.” P.S. […] The post When you believe in things that you don’t understand appeared first on…

The exponential family of distributions is important in Statistics because all the common distributions are of this type, and by the Pitman-Koopman theorem, they are exactly the family of distributions which has useful sufficient statistics. By an amaz...

Typing tables in LaTeX can get messy, but there are some good tools to simplify the process. One I discovered this week is tablesgenerator.com, a web-based tool for generating LaTeX tables. It also allows the table to saved in other formats including HTML and Markdown. The interface is simple, but it does most things. For complicated tables, some additional formatting may be necessary. Similar functionality is available via…

The programme of the forthcoming UK Causal Inference Meeting "Causal Inference in Health, Economic and Social Sciences" is just out. The short conference will be at the end of the month (28th and 29th of April) at the University of Cambridge.I ind...

Kevin Cartier writes: I’ve been happily using R for a number of years now and recently came across Stan. Looks big and powerful, so I’d like to pick an appropriate project and try it out. I wondered if you could point me to a link or document that goes into the motivation for this tool […] The post Transitioning to Stan appeared first on Statistical Modeling, Causal Inference, and Social…

But some difficulties do arise . . . Fri: One-tailed or two-tailed? Sat: Index […] The post On deck this week appeared first on Statistical Modeling, Causal Inference, and…

Trees. They’re everywhere. And not just in the physical world, but in data visualization and knowledge representation as well. This is not a new phenomenon, it goes back thousands of years. Manuel Lima’s new book, The Book of Trees, gives an overview. Setting Expectations This review is an example of priming. The first time I […]

A few days ago, the Centers for Medicare and Medicaid Services (CMS) released some unprecedented data on the US healthcare system. The data consists of 9 million rows showing how much each doctor in the US charged Medicare, for what, and how much Medicare paid out. It doesn't quite cover everything (for example, services with less than 11 beneficiaries were removed for privacy reasons), but its the best thing we've…
