Intermittent demand, Croston and Die Hard
I have recently been confronted to a kind of data set and problem that I was not even aware existed: intermittent demand data. Intermittent demand arises when the demand for a certain good arrives sporadically. Let’s take a look at an example, by analyzing the number of downloads for the {RDieHarder} package: library(tidyverse) library(tsinterm...

Curly-Curly, the successor of Bang-Bang
Writing functions that take data frame columns as arguments is a problem that most R users have been confronted with at some point. There are different ways to tackle this issue, and this blog post will focus on the solution provided by the latest release of the {rlang} package. You can read the announcement here, which explains really well what ...

Statistical matching, or when one single data source is not enough
I was recently asked how to go about matching several datasets where different samples of individuals were interviewed. This sounds like a big problem; say that you have dataset A and B, and that A contain one sample of individuals, and B another sample of individuals, then how could you possibly match the datasets? Matching datasets requires a c...

Using linear models with binary dependent variables, a simulation study
This blog post is an excerpt of my ebook Modern R with the tidyverse that you can read for free here. This is taken from Chapter 8, in which I discuss advanced functional programming methods for modeling. As written just above (note: as written above in the book), map() simply applies a function to a list of inputs, and in the previous section we...

Modern R with the tidyverse is available on Leanpub
Yesterday I released an ebook on Leanpub, called Modern R with the tidyverse, which you can also read for free here. In this blog post, I want to give some context. Modern R with the tidyverse is the second ebook I release on Leanpub. I released the first one, called Functional programming and unit testing for data munging with R around Christmas...
