Results from Tukey HSD test, with additional plot methods

Can also compute and plot additional post-hoc evaluations using this results class.


halfwidths is only available after call to plot_simultaneous.

Other attributes contain information about the data from the MultiComparison instance: data, df_total, groups, groupsunique, variance.

rejectarray of bool, True if we reject Null for group pair
meandiffspairwise mean differences
confintconfidence interval for pairwise mean differences
std_pairsstandard deviation of pairwise mean differences
q_critcritical value of studentized range statistic at given alpha
halfwidthshalf widths of simultaneous confidence interval
pvaluesadjusted p-values from the HSD test


plot_simultaneous([comparison_name, ax, ...])

Plot a universal confidence interval of each group mean
