Binning with Weights
After working on the MOB package, I received requests from multiple users if I can write a binning function that takes the weighting scheme into consideration. It is a legitimate...continue reading.
Batch Deployment of WoE Transformations
After wrapping up the function batch_woe() today with the purpose to allow users to apply WoE transformations to many independent variables simultaneously, I have completed the development of major functions...continue reading.
Le Monde puzzle [#1092]
A Latin square Le Monde mathematical puzzle that I found rather dreary: A hidden 3×3 board contains all numbers from 1 to 9. Anselm wants to guess the board and...continue reading.
Features in Stata 15: a collection of blog posts
After Stata 15 came out in the summer of ’17, I wrote a series of blog posts for Timberlake, the … Morecontinue reading.
Mediators, confounders, colliders – a crash course in causal inference
Although one would think that the basic concepts of statistics should be the same across all sciences, there is an amazing heterogeneity between fields in how statistics is taught and...continue reading.
Batch Processing of Monotonic Binning
In my GitHub repository (https://github.com/statcompute/MonotonicBinning), multiple R functions have been developed to implement the monotonic binning by using either iterative discretization or isotonic regression. With these functions, we can run...continue reading.
The Easiest Way to Create Thresholds And Improve Your Classification Model
You’d be surprised at how many data scientists don’t know how to turn their probabilities into class labels. Often times they will just go with 50% as the cutoff without...continue reading.

Data Science Software Used in Journals: Stat Packages Declining (including R), AI/ML Software Growing
In my neverending quest to track The Popularity of Data Science Software, it’s time to update the section on Scholarly Articles. The rapid growth of R could not go on...continue reading.
Monotonic Binning with GBM
In addition to monotonic binning algorithms introduced in my previous post (https://statcompute.wordpress.com/2019/03/10/a-summary-of-my-home-brew-binning-algorithms-for-scorecard-development), two more functions based on Generalized Boosted Regression Models have been added to my GitHub repository, gbm_bin() and...continue reading.
Quickly create Codeplans of your (labelled) Data #rstats
The view_df() function from the sjPlot-package creates nice „codeplans“ from your data sets, and also supports labelled data and tagged NA-values. This gives you a comprehensive, yet clear overview of your data set....continue reading.

Deployment of Binning Outcomes in Production
In my previous post (https://statcompute.wordpress.com/2019/03/10/a-summary-of-my-home-brew-binning-algorithms-for-scorecard-development), I’ve shown different monotonic binning algorithm that I developed over time. However, these binning functions are all useless without a deployment vehicle in production. During...continue reading.
Mango shares the power of R with Sainsbury’s Data Community
What’s in a Data Community? One of the UK’s top retailers, Sainsbury’s, knows just how much value can be derived from a community, which, when coming together in a data...continue reading.
