pub fn information_inverse(
information: &FlatMatrix,
diagonal: &[f64],
rows: usize,
) -> Result<InformationInverse, FittingError>Expand description
InformationInverse of information, the expected information of
rows counts, scaled to diagonal.
§Errors
FittingError::InvalidConfig if information is not square, does not
hold its entries, has an entry that is not finite, or is not symmetric to
1e-12 of √(dᵢdⱼ), or if diagonal is not one finite non-negative entry
per row, zero only on a row of zeros; FittingError::EvaluationFailed if its eigendecomposition
fails.
