statsmodels.stats.contingency_tables.SquareTable

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

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. These methods should only be used when the rows and columns of the table have the same categories. If `table` is provided as a Pandas DataFrame, the row and column indices will be extended to create a square table. Otherwise the table should be provided in a square form, with the (implicit) row and column categories appearing in the same order.

Methods
