Vizzy vizzy vizzy viz

Nadia Hassan points me to this post by Matthew Yglesias, who writes: Here’s a very cool data visualization from HowMuch.net that took me a minute to figure out because it’s a little bit unorthodox. The way it works is that it visualizes the entire world’s economic output as a circle. That circle is then subdivided […] The post Vizzy vizzy vizzy viz appeared first on Statistical Modeling, Causal Inference, and…

“Soylent 1.5” < black beans and yoghurt

Mark Palko quotes Justin Fox: On Monday, software engineer Rob Rhinehart published an account of his new life without alternating electrical current — which he has undertaken because generating that current “produces 32 percent of all greenhouse gases, more than any other economic sector.” Connection to the power grid isn’t all Rhinehart has given up. […] The post “Soylent 1.5” < black beans and yoghurt appeared first on Statistical Modeling,…

Survey weighting and regression modeling

July 14, 2015
By

Yphtach Lelkes points us to a recent article on survey weighting by three economists, Gary Solon, Steven Haider, and Jeffrey Wooldridge, who write: We start by distinguishing two purposes of estimation: to estimate population descriptive statistics and to estimate causal effects. In the former type of research, weighting is called for when it is needed […] The post Survey weighting and regression modeling appeared first on Statistical Modeling, Causal Inference,…

In which a complete stranger offers me a bet

Piotr Mitros wrote to Deb and me: I read, with pleasure, your article about the impossibility of biasing a coin. I’m curious as to whether researchers believe what they write. Would you be willing to place some form of iterated bet? For example: I provide a two-sided coin and a table. The table looks like […] The post In which a complete stranger offers me a bet appeared first on…
