The debt ceiling was always an issue in the United States. As of today, the national government debt has reached the debt ceiling, which is $31.4 trillion. The authorities have warned of chaotic consequences if Congress no longer approves the debt ceiling. The U.S. government has managed an annual deficit ...

smooth package has reached version 3.2.0 and is now on CRAN. While the version change from 3.1.7 to 3.2.0 looks small, this has introduced several substantial changes and represents a first step in moving to the new C++ code in the core of the functions. In this short post, I will outline the ...

Winter started a bit more than one month ago… but we have already experienced many snow storms… there is still a lot snow in gardens and in the streets, I was wondering if it was that unusual, but apparently not. Compared with last year, it is (for the first months ...

In my last post ‘GooglyPlusPlus now with Win Probability Analysis for all T20 matches‘ I had discussed the performance of my ML models, created with and without player embeddings, in computing the Win Probability of T20 matches. With batsman & bowler embeddings I got much better performance than without the embeddings ...

As an independent consultant the majority of my work is about solving novel problems faced by my clients. At a basic level, a client has a question they need answered or a problem they’d like solved and my job is to develop something that meets their needs (given the ...

As I finished grading our undergrad math stats exam (in Paris Dauphine) over the weekend, which was very straightforward this year, the more because most questions had already been asked on weekly quizzes or during practicals, some answers stroke me as atypical (but ChatGPT is not to blame!). For instance, ...

tidymodels and shapviz to explain XGBoost models

What do we mean by “responsiveness”? Confusingly (and rather unhelpfully) when it comes to web applications there are two different topics that may be referred to by the terms “r...

After much deliberation, I have updated my personal R code style guide to no longer mandate functions begin with uppercase letters. While I still feel there is value in being able immediately differentiate functions from variables, too much of base R does not follow that convention and one loses more ...
