An S7 class produced by TTEST pipelines using x_by() as the variable mapper <var_id>.
Not constructed manually — use the pipeline instead.
Inherits from class_stat_infer, so auto_tidy() dispatches on it
automatically. Downstream packages can use it as a parent in
S7::new_class().
Details
Slots (populated automatically by TTEST):
group: name of the grouping variable.estimate: mean difference (or linear contrast estimate).t_stat: t-statistic.df: degrees of freedom.p_val: p-value.lower_ci: lower confidence bound.upper_ci: upper confidence bound.ci_level: confidence level, e.g.0.95.
Shared by variants
Both the default (base) and contrast return a class_ttest_two, so
auto_tidy() and print() are inherited by contrast for free.
