Simulated long-format data for paired analyses. Each participant has a
Baseline and Follow-up record. pain_score supports a paired t-test example,
days_off_work is skewed for a signed-rank example, and symptom_present
supports McNemar's test.
Format
A data frame with 180 rows (90 complete pairs) and 5 variables:
id, visit, pain_score, days_off_work, and symptom_present.
Examples
compare_groups(
paired_data, variable = pain_score, group = visit,
paired = TRUE, id = id
)
compare_groups(
paired_data, variable = symptom_present, group = visit,
paired = TRUE, id = id
)
