Benjamin Trent cf151b53fe [ML] adds new change_point pipeline aggregation (#83428) ... adds a new `change_point` sibling pipeline aggregation. This aggregation detects a change_point in a multi-bucket aggregation. Example: ``` POST kibana_sample_data_flights/_search { "size": 0, "aggs": { "histo": { "date_histogram": { "field": "timestamp", "fixed_interval": "3h" }, "aggs": { "ticket_price": { "max": { "field": "AvgTicketPrice" } } } }, "changes": { "change_point": { "buckets_path": "histo>ticket_price" } } } } ``` Response ``` { /*<snip>*/ "aggregations" : { "histo" : { "buckets" : [ /*<snip>*/ ] }, "changes" : { "bucket" : { "key" : "2022-01-28T23:00:00.000Z", "doc_count" : 48, "ticket_price" : { "value" : 1187.61083984375 } }, "type" : { "distribution_change" : { "p_value" : 0.023753965139433175, "change_point" : 40 } } } } } ```		2022-03-04 07:00:58 -05:00
