pub fn classify(
rank: usize,
n_params: usize,
redundancy: i32,
condition_number: f64,
gdop: f64,
has_valid_prior: bool,
thresholds: GeometryQualityThresholds,
) -> GeometryQualityExpand description
Classify geometry observability and covariance validation from scalar diagnostics.
rank is compared to n_params. redundancy is n_obs - n_params.
condition_number must be the singular-value ratio of the design matrix,
not the condition number of the normal matrix. A non-finite condition number,
GDOP, or cutoff is treated as exceeding the corresponding cutoff for
full-rank positive-redundancy cases.
