Contingency Table for multidimensional arrays

Computed contingency table as defined as,

\[\begin{split}\begin{array}{c|c|c|c} & y = 1 & y = 0 & \text{Total} \\ \hline x = 1 & n_{11} & n_{10} & n_{1\bullet} \\ x = 0 & n_{01} & n_{00} & n_{0\bullet} \\ \hline \text{Total} & n_{\bullet1} & n_{\bullet0} & n \end{array}\end{split}\]

Parameters:

• first_var (DataArray) – First binary variable

• second_var (DataArray) – Second binary variable

• sum_over (str) – Dimension to sum over to compute the number of observations

Returns:

Instance of ContingencyTable

Return type:
