Hi folks, Has anyone used VarianceThresholdSelector refer to https://spark.apache.org/docs/latest/ml-features.html#variancethresholdselector <https://spark.apache.org/docs/latest/ml-features.html#variancethresholdselector> ? In the doc, an example is gaven and says `The variance for the 6 features are 16.67, 0.67, 8.17, 10.17, 5.07, and 11.47 respectively`, but after calculating I found that the variance should be 13.89, 0.56, 6.81, 8.47, 4.22, 9.56, and there should be only 3 columns selected. Is there something wrong with me or this is a bug?
Regards, Xin
