Members

isBincountable eponymoustemplate isBincountable(T): bincountable type is a one-dimentional slice with unsigned elements

bincount auto bincount(T xs, size_t minlength): Count number of occurrences of each value in slice of non-negative ints.
bincount auto bincount(T xs, W weights, size_t minlength): Count weighted number of occurrences of each value in slice of non-negative ints. Note that empty weight causes compiler error.
gmean deprecated auto gmean(S slice): Computes the geometric mean of a slice. The product in gmean is computed in logarithms to avoid FP overflows.
gmean deprecated auto gmean(S slice, Seed seed): Computes the geometric mean of a slice.
mean deprecated auto mean(S slice): Undocumented in source. Be warned that the author may not have intended to support it.
mean deprecated auto mean(S slice, Seed seed): Undocumented in source. Be warned that the author may not have intended to support it.
median auto median(S x): Undocumented in source.

center deprecated template center(sumTemplateArgs...): Lazily centers a slice.
hmean deprecated template hmean(sumTemplateArgs...): Computes the harmonic mean of a slice.
logsumexp template logsumexp(sumTemplateArgs...): Computes the log of the sum of exponentials of input elements.
mean deprecated template mean(sumTemplateArgs...): Undocumented in source.
moment template moment(sumTemplateArgs...): Computes the n-th central moment of a slice.
std deprecated template std(sumTemplateArgs...): Computes the standard deviation of a slice.
var deprecated template var(sumTemplateArgs...): Computes the variance of a slice.
zscore template zscore(sumTemplateArgs...): Computes the zscore of a slice.
