tdigest commands (14/14 implemented)¶
TDIGEST.CREATE¶
Allocates memory and initializes a new t-digest sketch
TDIGEST.RESET¶
Resets a t-digest sketch: empty the sketch and re-initializes it.
TDIGEST.ADD¶
Adds one or more observations to a t-digest sketch
TDIGEST.MERGE¶
Merges multiple t-digest sketches into a single sketch
TDIGEST.MIN¶

TDIGEST.CDF¶
Returns, for each input value, an estimation of the fraction (floating-point) of (observations smaller than the given value + half the observations equal to the given value)
TDIGEST.TRIMMED_MEAN¶
Returns an estimation of the mean value from the sketch, excluding observation values outside the low and high cutoff quantiles
TDIGEST.RANK¶
Returns, for each input value (floating-point), the estimated rank of the value (the number of observations in the sketch that are smaller than the value + half the number of observations that are equal to the value)
