Background:

Analysis of two-way contingency tables is crucial for understanding pairwise interactions.
A deterministic model has been proposed, decomposing interaction counts into selective and random components.

Purpose of the Study:

To critically review the proposed deterministic model for analyzing contingency tables of pairwise interactions.
To identify inherent problems within the deterministic model's framework.
To propose a suitable alternative for analyzing such data.

Main Methods:

Review and critique of a deterministic model for contingency table analysis.
Identification of issues related to non-unique decomposition, parameter estimation, and hypothesis testing.
Exploration of generalized linear models as an alternative approach.

Main Results:

The deterministic model suffers from non-unique decomposition, hindering parameter estimation and interpretation.
The deterministic framework lacks a foundation for statistical estimation and hypothesis testing.
The assumption of decomposibility is not supported by empirical or theoretical evidence.

Conclusions:

The reviewed deterministic model is problematic for analyzing pairwise interaction data in contingency tables.
Generalized linear models offer a more statistically sound and flexible alternative.
Proper specification of the probability process and removal of overparameterization are key for effective analysis.
