## New package: simfinR

October 31, 2019
By

Introduction In my latest post I wrote about package GetEdgarData, which downloaded structured data from the SEC. I’ve been working on this project and soon realized that the available data at the SEC/DERA section is not complete. For example, all Q4 statements are missing.

## A brief primer on Variational Inference

October 30, 2019
By

Bayesian inference using Markov chain Monte Carlo methods can be notoriously slow. In this blog post, we reframe Bayesian inference as an optimization problem using variational inference, markedly speeding up computation. We derive the variational objective function, implement coordinate ascent mean-field variational inference for a simple linear regression example in R, and compare our results to results obtained via...

## The Mysterious Case of the Ghost Interaction

This spooky post was written in collaboration with Yoav Kessler (@yoav_kessler) and Naama Yavor (@namivor).. Experimental psychology is moving away from repeated-measures-ANOVAs, and towards linear mixed models (LMM1). LMMs have many advantages over rmANOVA, including (but not limited to): Analysis of single trial data (as opposed to aggregated means per condition). Specifying more than one random factor (typically crossed random intercepts of...

## Non-randomly missing data is hard, or why weights won’t solve your survey problems and you need to think generatively

$Non-randomly missing data is hard, or why weights won’t solve your survey problems and you need to think generatively$

Throw this onto the big pile of stats problems that are a lot more subtle than they seem at first glance. This all started when Lauren pointed me at the post Another way to see why mixed models in survey data are hard on Thomas Lumley’s blog. Part of the problem is all the jargon

## Enlarging the eBook supply

October 29, 2019
By

There has been a campaign by members of the Canadian library community to ask international publishers to reduce prices to libraries for eBooks.  If my experience in the scientific publishing arena is any guide, the publishers will continue to charge the maximum they can get until the marketplace — that is us — forces them…
