- Example::
>>> df = session.create_dataframe([1,2,3,4,5], schema=["a"]) >>> df.select(approx_percentile_accumulate("a").alias("result")).show() ------------------------------ |"RESULT" | ------------------------------ |{ | | "state": [ | | 1.000000000000000e+00, | | 1.000000000000000e+00, | | 2.000000000000000e+00, | | 1.000000000000000e+00, | | 3.000000000000000e+00, | | 1.000000000000000e+00, | | 4.000000000000000e+00, | | 1.000000000000000e+00, | | 5.000000000000000e+00, | | 1.000000000000000e+00 | | ], | | "type": "tdigest", | | "version": 1 | |} | ------------------------------
