Assoc

The assoc module provides association models for cohort analyses, including Cox, logistic, linear, subgroup, trend, competing-risk, and lagged exposure workflows.

Scope

Group	Functions
Main models	assoc_coxph(), assoc_logistic(), assoc_linear()
Aliases	assoc_cox(), assoc_logit(), assoc_lm()
Diagnostics	assoc_coxph_zph(), assoc_zph()
Extensions	assoc_subgroup(), assoc_trend(), assoc_competing(), assoc_lag()
Short aliases	assoc_sub(), assoc_tr(), assoc_fg()

Workflow Role

Most workflows start from a derived cohort table with event, time, exposure, and covariate columns. The main model functions return tidy result tables that can be passed directly to plot_forest() or used as summary-level outputs.

Review Focus

• strict validation of outcome, time, exposure, and covariate columns;
• stable three-model adjustment behavior;
• explicit handling of logical and 0/1 outcomes;
• consistent CI and p-value formatting for downstream plots.
