Parameters: col - 用数表示的列的name probabilities-a list of quantile probabilities Each number must belong to [0, 1]. For example 0 is the minimum, 0.5 is the median, 1 is the maximum. relativeError - The relative target precision to achieve (>= 0).If set to zero, the exact quanti...
我们可以使用setMaster()函数来设置要连接的主 URL。我们可以使用setAppName()函数来设置应用程序名称,并使用setSparkHome()来设置 Spark 将安装在工作节点上的路径。 您可以在spark.apache.org/docs/0.9.0/api/pyspark/pysaprk.conf.SparkConf-class.html了解更多关于 SparkConf 的信息。 摘要 在本章中,我们学习...
# summary of the test including the p-value, test statistic, and null hypothesis # if our p-value indicates significance, we can reject the null hypothesis # Note that the Scala functionality of calling Statistics.kolmogorovSmirnovTest with # a lambda to calculate the CDF is not made available...
在这个意义上，我们可以在Pyspark中找到一种以不同方式执行SET操作的方法。“SET”意味着根据过滤器（或...
relativeError - The relative target precision to achieve (>= 0).If set to zero, the exact quantiles are computed, which could be very expensive. Note that values greater than 1 are accepted but give the same result as 1. Returns: the approximate quantiles at the given probabilities ...
