statsmodels.stats.contingency_tables.SquareTable

class statsmodels.stats.contingency_tables.SquareTable(table, shift_zeros=True)

Methods for analyzing a square contingency table.

Parameters:

• table (array-like) – A square contingency table, or DataFrame that is converted to a square form.
• shift_zeros (boolean) – If True and any cell count is zero, add 0.5 to all values in the table.
• methods should only be used when the rows and columns of the (These) –
• have the same categories. If table is provided as a (table) –
• DataFrame, the row and column indices will be extended to (Pandas) –
• a square table, inserting zeros where a row or column is (create) –
• Otherwise the table should be provided in a square form, (missing.) –
• the (implicit) row and column categories appearing in the (with) –
• order. (same) –
