cts:percentilects:percentile( $arg as xs:double*, $p as xs:double* ) as xs:double*

Returns a sequence of percentile(s) given a sequence of percentage(s).
This function works like `math:percentile`

except each item in
the sequence is repeated `cts:frequency`

times before calculating
the percentile(s). The function returns the empty sequence if either $arg
or $p is the empty sequence.

Parameters | |
---|---|

arg | The sequence of values. The values should be the result of a lexicon lookup. |

p | The sequence of percentage(s). |

This function is designed to take a sequence of values returned
by a lexicon function (for example, `cts:element-values`

); if you
input non-lexicon values, the result will be the empty sequence.

xquery version "1.0-ml"; (: This query assumes an element range index of type 'int' is configured for the 'int' element in the database. It generates some sample data and then performs the aggregation in a separate transaction. :) for $x in 1 to 10 return xdmp:document-insert(fn:concat($x, ".xml"), <my-element>{ for $y in 1 to $x return <int>{$x}</int> }</my-element>); cts:percentile(cts:element-values(xs:QName("int"), (), ("type=int", "item-frequency")), (0.25,0.5,0.75)) => 5,7,9
