# Statistical references Primary literature is cited in the method-specific validation ledgers. This site keeps references close to the formulas they support so readers can audit the path from publication to implementation. ```{bibliography} :all: ``` ## Software and comparison sources - [NumPy documentation](https://numpy.org/doc/stable/) - [SciPy statistics documentation](https://docs.scipy.org/doc/scipy/reference/stats.html) - [SHT 0.1.9 source](https://github.com/kisungyou/SHT) Agreement with another package is supporting evidence, not the sole correctness criterion. Each pySHT validation record states exactly what an external comparison establishes.
