Basic stats utils. Private, subject to change.

all-format-columns clj/s

default-format-columns clj/s

default-format-id-fn clj/s

get-max-id-width clj/s

(get-max-id-width id-sstats*
                  {:keys [format-id-fn]
                   :or {format-id-fn default-format-id-fn}})

sstats clj/s

(sstats nums)

Given a coll of numbers, returns a new mergeable ?SummaryStats with: (deref ss) => {:keys [n min max p25 ... p99 mean var mad]}

See also summary-stats-merge.

sstats-format clj/s

(sstats-format clock-total
               id-sstats*
               {:keys [columns sort-fn format-id-fn max-id-width]
                :as opts
                :or {columns default-format-columns
                     sort-fn (fn [ss] (get (enc/force-ref ss) :sum))
                     format-id-fn default-format-id-fn}})

Given {<id> <sstats>} or {<id> <sstats-map>}, returns a formatted table string. Assumes nanosecond clock, and stats based on profiling id'd nanosecond times.

sstats-merge clj/s

(sstats-merge ss1)

(sstats-merge ss1 ss2)

Given one or more SummaryStats, returns a new ?SummaryStats with: (summary-stats-merge (summary-stats nums1) (summary-stats nums2))

an approximatation of (summary-stats (merge nums1 nums2))

Useful when you want summary stats for a large coll of numbers for which it would be infeasible/expensive to keep all numbers for accurate merging.
