I’ve spent a lot of time mocking Mark Hauser on this blog, and I still find it annoying that, according to the accounts I’ve seen, he behaved unethically toward his graduate students and lab assistants, he never apologized for manipulating data, and, perhaps most unconscionably, he wasted the lives of who knows how many monkeys […] The post Redemption appeared first on Statistical Modeling, Causal Inference, and Social Science.

An auto-mechanic-style sign for data sharing

Yesterday’s story reminds me of that sign you used to see at the car repair shop: Maybe we need something similar for data access rules: DATA RATES PER HOUR If you want to write a press release for us $ 50.00 If you want to write a new paper using our data $ 90.00 If […] The post An auto-mechanic-style sign for data sharing appeared first on Statistical Modeling, Causal…

Compute nearest neighbors in SAS

Finding nearest neighbors is an important step in many statistical computations such as local regression, clustering, and the analysis of spatial point patterns. Several SAS procedures find nearest neighbors as part of an analysis, including PROC LOESS, PROC CLUSTER, PROC MODECLUS, and PROC SPP. This article shows how to find […] The post Compute nearest neighbors in SAS appeared first on The DO Loop.

Link: xkcd’s Earth Temperature Timeline

Randall Munroe has done it again. His latest xkcd comic is an enormous timeline of the Earth's temperature, showing the enormously long time we have temperature estimates for, and how little it has changed until very, very recently. Munroe has an incredible talent for creating simple and fun explanations for complex topics. I highly recommend his book, Thing Explainer. […]

Insufficient statistics

September 12, 2016
By

Experience with the normal distribution makes people think all distributions have (useful) sufficient statistics [1]. If you have data from a normal distribution, then the sufficient statistics are the sample mean and sample variance. These statistics are “sufficient” in that the entire data set isn’t any more informative than those two statistics. They effectively condense […]

Overlay a curve on a bar chart in SAS

One of the strengths of the SGPLOT procedure in SAS is the ease with which you can overlay multiple plots on the same graph. For example, you can easily combine the SCATTER and SERIES statements to add a curve to a scatter plot. However, if you try to overlay incompatible […] The post Overlay a curve on a bar chart in SAS appeared first on The DO Loop.
