CodePen, AngularJS, and Jasmine!

Online Web editors, like JSbin, plnkr, and CodePen, are awesome. They allow you to easily work on an idea without all of the muss and fuss of having to spin up a server. You can also share the idea with friends or the entire Internet easily.

HTS with Regressors

The hts pack­age for R allows for fore­cast­ing hier­ar­chi­cal and grouped time series data. The idea is to gen­er­ate fore­casts for all series at all lev­els of aggre­ga­tion with­out impos­ing the aggre­ga­tion con­straints, and then to rec­on­cile the fore­casts so they sat­isfy the aggre­ga­tion con­straints.

Removing Uncited References in a Tex File (with R)

Usually, once you have revised the paper, some references were added, others were dropped. But you need to spend some time to check that all references are actually mentioned in the paper. I wanted to work on that manually this week-end, but @3wen suggested to write a simple R function to scan the tex f file (as well as the aux file actually) to remove uncited references.

As I’ve written in the past, I put an awful lot of effort into making Have I been pwned? (HIBP) fast. Not just a bit fast, blisteringly fast and that includes when it’s under a huge amount of load. But there was something bugging me with the site when it came to performance and it was this:

Andrews Curves

Andrews curves are a method for visualizing multidimensional data by mapping each observation onto a function. It has been shown the Andrews curves are able to preserve means, distance (up to a constant) and variances. Which means that Andrews curves that are represented by functions close together suggest that the corresponding data points will also be close together.

Experts vs Professionals

Working with professionals can be a joy. Not only can they solve your problem, they may help you see what problem you should solve. Experts, however, are not always so pleasant to work with.

R: Linear models with the lm function, NA values and Collinearity

In my continued playing around with R I’ve sometimes noticed ‘NA’ values in the linear regression models I created but hadn’t really thought about what that meant. On the advice of Peter Huber I recently started working my way through Coursera’s Regression Models which has a whole slide explaining its meaning:
