After the day

The methods strand of the companion curriculum takes each model and each argument of the day further.

If you want	Read
Every model on the menu, output by output, including the multilevel, Bayesian and beta-regression sections that the day only names	The statistical methods behind the course
The graph work at a slower pace, and a graph for a question of your own	Causal graphs
The measurement decisions that the menu opened	Weights, Missing answers and The items behind the scales
The multiverse debate in full, with the 2025–26 critics read against the course grid	The multiverse and its critics
Data generated from known values, to test what a method recovers	Simulation as a method
The same claim at the individual level	The individual level
To archive and version the report you wrote	Reproducibility repositories, then Git and GitHub
To find the data for a project of your own, or to obtain the data behind this one	Social science data sources

The replication-focused day is the original balance of this course, the tools-focused day gives the toolchain the time that this day gives the statistics, and the three-day format does both.
