This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Quarto-based Beamer slide decks for the "Introduction to Statistical Modeling" course. QMD files render to PDF via LuaTeX.

Build Commands

# Render all slides
quarto render

# Render a single slide deck
quarto render 01a-regression-intro.qmd

# Preview with live reload
quarto preview 01a-regression-intro.qmd

Output goes to pdfs/ directory. Quarto uses freeze: auto so cached results in _freeze/ are only regenerated when source changes.

Slide Naming Convention

Files follow [chapter][letter]-[topic].qmd:

  • 01a-g: Linear regression (intro, simple, multiple, predictivity, outliers, categorical, multicollinearity)
  • 02a-d: PCA and logistic regression
  • 03a-f: Nonlinear regression, model selection, sensitivity analysis, Monte Carlo

Slide Format

All QMD files use identical Beamer YAML frontmatter:

format:
  beamer:
    theme: Pittsburgh
    colortheme: default
    fonttheme: default
    include-in-header:
      - file: header.tex
    pdf-engine: lualatex

header.tex adds left-aligned frame titles, slide numbers, emoji support, and Korean language support via luatexko. The lualatex engine is required.

Key Directories

  • datasets/ — CSV, RDA, XLSX data files used in examples
  • scripts/ — R helper functions (regression, parameter estimation, sensitivity analysis)
  • images/ — Static images organized by topic
  • _freeze/ — Quarto render cache (auto-managed)
  • case-studies/ — Supporting R materials

R Environment

R dependencies are managed with renv. Key packages: tidyverse, ggplot2, car, MASS, caret, glmnet, pROC, plot3D.

# Restore R environment
Rscript -e "renv::restore()"
