I am delighted to announce publication of the 4th edition of Linear Algebra Done Right as an Open Access book. The electronic version is legally free to the world at linear.axler.net. That website also has links to pre-order the print version of the book. #linearalgebra

Abigail Marsh @diegoareinero Thanks for your interest! We also published a letter in PNAS about 10 days ago on this topic: pnas.org/doi/10.1073/pn…

If you are in the market for a quant postdoc, I am jealous … Very cool opportunity! Move to Europe, work on cool SAM models, and be supervised by Yves Rosseel, the developer of lavaan.

Gino's case against us has been dismissed. Scientists cannot effectively sue other scientists for exposing fraud/errors in their work. Those who work to correct the scientific record can sleep better tonight. Those who don’t want it corrected, well, I don’t care how they sleep.

An antidote for: If you've got too many people coming to your door, saying, "A quick stats question; it'll only take a minute" ...
