wishmom 1.2.0 (2026-09-09)
iwishmom(): corrected the existence test for inverse moments. The moment of
total degree k = sum_j j*f_j + iw exists if and only if (n-m+1)/alpha > k,
i.e. n1 = n-m+1-alpha > (k-1)*alpha (real case n-m+1 > 2k, complex case
n-m+1 > k). Versions 1.0-1.1 used n1 > 2k and returned NaN for some moments
that exist.
wishmom_sym(): the printed coefficients were all divided by n (the
formatting routine treated the coefficient of n as a constant term). The
numerical function wishmom() was not affected. iwishmom_sym() was correct.
wishmom(), iwishmom(): the degenerate case k = 0 now returns m (or the
identity matrix).
- Vignette: corrected the statement of the existence condition; regenerated
the
wishmom_sym() example outputs from the corrected code; fixed a typo
in the iwish_psr() example (iwsih_psr -> iwish_psr) and in the
description of its k argument.
