Chasing the noise:  W. Edwards Deming would be spinning in his grave

Amy Cohen writes: A surgeon showed me the “report card” his hospital received about his surgical group. The figure below shows what the report card looks like. I am very curious to hear what you think about the “deciles of the odds ratio” approach to evaluate and rank hospitals used by the American College of […]The post Chasing the noise: W.

Limiting scope paradoxically makes a problem harder

I left a comment on one of Andrew Gelman's recent posts about Malcolm Gladwell (link). This post discusses briefly a review of Gladwell's recent book. A commenter ("Haile") made the following defense of Gladwell: My point is that many of these criticisms are based on Gladwell’s failure to present rigorous statistical evidence of arguments that are not statistical in nature in the first place. when (if) reading Gladwell, it’s time…

Rob “Lasso” Tibshirani writes: We all read a lot of papers and often have useful things to say about them, but there is no systematic way to do this ­ lots of journals have commenting systems, but they’re clunky, and, most importantly, they’re scattered across thousands of sites.

Output percentiles of multiple variables in a tabular format

A challenge for statistical programmers is getting data into the right form for analysis. For graphing or analyzing data, sometimes the "wide format" (each subject is represented by one row and many variables) is required, but other times the "long format" (observations for each subject span multiple rows) is more [...]

GLM, non-linearity and heteroscedasticity

If we visualize that linear…
