Package index

Estimation

Estimate event-study curves, aggregated ATT, and basic two-way FE DiD.

event_study()

Event study estimation for panel data

att()

ATT aggregation for staggered adoption designs

did()

Basic two-way fixed-effects DiD estimation

Sensitivity analysis

Robust inference under violations of parallel trends.

honest_sensitivity()

Honest sensitivity analysis for parallel-trends violations

Diagnostics

ATT(g,t) extraction and contamination-weight diagnostics for the Sun-Abraham estimator.

att_gt()

Extract the ATT(g,t) table from a Callaway-Sant'Anna result

contamination_weights()

Contamination Weights for TWFE Event-Study Coefficients (Sun-Abraham 2021)

Visualization

Base plot() methods for every result class (static ggplot2; use interactive = TRUE for plotly event-study charts).

plot(<es_result>)

plot(<att_result>) autoplot(<att_result>)

Plot an ATT aggregation result

plot(<att_gt_result>) autoplot(<att_gt_result>)

plot(<honest_result>) autoplot(<honest_result>)

Plot a honest sensitivity analysis

plot(<sa_contamination_weights>)

Plot contamination weights as a tile heatmap

S3 methods

broom and ggplot2 integration for result objects.

autoplot(<es_result>)

Autoplot for event-study results

tidy(<es_result>)

Tidy an es_result object

glance.es_result()

Glance at an es_result object

tidy(<did_result>)

Tidy a did_result object

glance.did_result()

Glance at a did_result object

tidy(<att_result>)

Tidy an att_result object

glance.att_result()

Glance at an att_result object
