  "Description": "Fast, numerically robust computation of weighted moments\nvia 'Rcpp'. Supports computation on vectors and matrices, and\nMonoidal append of moments. Moments and cumulants over running\nfixed length windows can be computed, as well as over\ntime-based windows. Moment computations are via a\ngeneralization of Welford's method, as described by Bennett et.\n(2009) <doi:10.1109/CLUSTR.2009.5289161>.",
