contingency_table computed from compute_contingency_table doesn’t contain both True and False for the observed or the simulated series

[xfeng2021]

The following line in function compute_contingency_table:

ctab = pd.crosstab(observed, simulated, dropna=False)
produces ctab containing only True or False for either the observed or the simulated series? It would cause the error in ctab.loc.

Could you add a solution to handle such situation?

Verified if either of the input categorical series contain only True or False, then compute_contingency_table fails with a KeyError for the missing boolean category.
