Computes the maximum absolute off-diagonal Tucker congruence coefficient
between subject-mode components in an ACMTF model. This metric serves as a
diagnostic tool to detect potential degeneracy in the subject-mode loadings.
Arguments
- A
A numeric matrix of subject-mode loadings (dimensions: subjects x components).
Value
A numeric scalar representing the maximum absolute off-diagonal
Tucker congruence between components.
Details
A high degenScore
(e.g., > 0.85) indicates that two or more components
in the subject mode are highly similar, suggesting a possible degeneracy or
lack of uniqueness. A low value (e.g., < 0.3) indicates well-separated components.
Examples
# Example: Compute degenScore for a random loading matrix
A <- matrix(rnorm(100), nrow = 10, ncol = 10)
degenScore(A)
#> [1] 0.7334973
