R on Windows made faster Continue reading: R Batteries Included (R 4.6.1 with OpenBLAS and Intel MKL)
This series has used a few survey statistics textbooks, see my list below. Which of your favorites am I missing ? Kish 1965: Särndal, Swensson, Wretman 1992: Groves et al. 2009: Lu...
Last week we discussed SynthMargins, a method from the poster Modeling Complex Contingency Tables that uses partial information (margins) about poststratification variables. On the...
Last month Andrew wrote: I use simulated data to understand how a model works; it can be viewed as a form of mathematical analysis, a way of working out the implications of a set o...

Rico Mariani, a long-time performance engineer at Microsoft, coined the idea of the pit of success. A system has a pit of success when the natural, lazy way of using it leads to go...
If you've written the same block of R code three times this week — a group summary, a plot, a cleanup step — you don't need another package. You need a function. A custom function...

Flow cytometry researchers have a growing collection of R and Bioconductor tools available to them. But for someone who is comfortable working with cytometry data and has little pr...
This post presents a function `mlReserve()` for machine-learning loss reserving on 'real-world' triangles, based on a fork of the 'ChainLadder' package. It includes two experiments...
Gustavo pointed us to this project (see also here) by David Dorer to impute data to lower census levels (block/tract) from PUMAs (public use microdata areas, as defined by the U.S....
In my last post on permute, I looked at ordered set partitions and the new formula interface for plots and blocks. This time I want to show two helpers for the next part of writing...
There is a quote I really love from Marc Kéry’s book, “Introduction to WinBUGS for Ecologists” (2010, p. 11): “WinBUGS helps free the modeler in you.” And it’s so true! Once you de...
Three hundred fifty-three new packages were submitted to CRAN in July. Here are my Top 40 picks in nineteen categories: Causal Inference, Chemistry, Climate Studies, Computational...
