To cite spectralDEMATEL in publications, use the concept DOI, which
always resolves to the newest release:

  Delias P (2026). _spectralDEMATEL: Spectral Diagnostics for DEMATEL
  Influence Matrices_. doi:10.5281/zenodo.21849277
  <https://doi.org/10.5281/zenodo.21849277>. R package version 0.6.0.

A BibTeX entry for LaTeX users is

  @Manual{,
    title = {spectralDEMATEL: Spectral Diagnostics for DEMATEL Influence Matrices},
    author = {Pavlos Delias},
    year = {2026},
    note = {R package version 0.6.0},
    doi = {10.5281/zenodo.21849277},
  }

Where the exact version matters -- reproducing a published number, say
-- cite the version DOI instead. Every release has its own; the concept
DOI above resolves to the newest record, which shows it.
