Identifiability Constraints in Generalized Additive Models

This repository contains code for reproducing the analysis in the paper Identifiability Constraints in Generalized Additive Models, published in the Canadian Journal of Statistics (open-access):

Stringer, A. (2023). Identifiability Constraints in Generalized Additive Models. Canadian Journal of Statistics (to appear).

Preparation

The code requires the following packages:

install.packages(
  "tidyverse",
  "here",
  "mgcv",
  "TMB",
  "Matrix",
  "parallel",
  "gamair"
)

Note: the here package is only required for portability of relative file paths, to make it a little easier to execute these scripts yourself. It isn't required to reproduce the results in the paper.

Code

The analyses are reproduced by the following scripts:

• Section 4.1: 01-gaussian-simulations.R
• Section 4.2: 02-poisson-simulations.R, 03-bernoulli-simulations.R
• Section 5: 04-chicago.R
