如何在PySpark中对百分位数进行聚合？

from pyspark.sql import SparkSession
from pyspark.sql.functions import approxQuantile

spark = SparkSession.builder.getOrCreate()

data = [(1,), (2,), (3,), (4,), (5,)]
df = spark.createDataFrame(data, ["value"])

percentiles = [0.25, 0.5, 0.75]  # 需要计算的百分位数列表
relativeError = 0.01  # 相对误差
result = df.approxQuantile("value", percentiles, relativeError)

for i in range(len(percentiles)):
    print(f"{percentiles[i]} percentile: {result[i]}")
