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

(summary-stats-buffered)(summary-stats-buffered {:keys [buffer-size buffer-init sstats-init merge-cb]
:or {buffer-size 100000.0}
:as opts})Returns a new stateful SummaryStatsBuffered with: (ssb <num>) => Adds given number to internal buffer. (deref ssb) => Flushes buffer if necessary, and returns a ?map of summary stats for all numbers ever added to ssb: {:keys [n min max p25 ... p99 mean var mad]}.
Useful for summarizing a (possibly infinite) stream of numbers. Used by the Tufte profiling library, and the Carmine Redis library.
Options: :buffer-size - The maximum number of numbers that may be buffered before next (ssb <num>) call will block to flush buffer and merge with any existing summary stats.
Larger buffers mean better performance and more
accurate stats, at the cost of more memory use.
:buffer-init - Initial buffer content, useful for persistent ssb. :sstats-init - Initial summary stats, useful for persistent ssb.

(summary-stats-merge ss1)(summary-stats-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.
