NM-METHOD FOR CONSTRUCTING COUNTERFACTUAL CONTINGENCY TABLES
Draft:NM-method; Naszodi–Mendonca method; Naszodi-Mendonca method
The NM-method or Naszodi–Mendonca method is the operation that can be applied in statistics, econometrics, economics, sociology, and demography to construct counterfactual contingency tables. The method finds the matrix X ( X \in \mathbb{R}^{n \times m } ) which is “closest” to matrix Z ( Z \in \mathbb{N}^{n \times m } called the seed table) in the sense of being ranked the same but with the row and column totals of a target matrix Y ( Y \in \mathbb{N}^{n \times m }) .
