quantilesGK

quantilesGK works similarly to quantileGK but allows us to calculate quantities at different levels simultaneously and returns an array.

Syntax

quantilesGK(accuracy, level1, level2, ...)(expr)

Returned value

Array of quantiles of the specified levels.

Type of array values:

Float64 for numeric data type input.
Date if input values have the Date type.
DateTime if input values have the DateTime type.

Example

Query:

SELECT quantilesGK(1, 0.25, 0.5, 0.75)(number + 1)
FROM numbers(1000)
