ENH: special: Add inverse of digamma function by fbourgey · Pull Request #25188 · scipy/scipy · GitHub adds the inverse of the digamma function as a new special function.
Why is it useful?
- Appears in common statistical estimation problems (Gamma, Beta, Dirichlet)
- Complement SciPy’s existing digamma API
- Avoid repeated ad hoc custom implementations
