机器学习PAI这个结果怎么不对？我就屏蔽了测试一下，然后发现结果好像不对再就是把label那一列删了[阿里云机器学习PAI]

如图，机器学习PAI这个结果怎么不对？

import com.alibaba.alink.operator.stream.StreamOperator;

//public class KSigmaOutlierStreamOpTest extends AlinkTestBase {
public class KSigmaOutlierStreamOpTest {

public void test() throws Exception {
List mTableData = Arrays.asList(
Row.of(1, new Timestamp(1000), 0.0),

    MemSourceStreamOp dataOp = new MemSourceStreamOp(mTableData, new String[] {"id", "ts", "val"});

    KSigmaOutlierStreamOp outlierOp = new KSigmaOutlierStreamOp()
            .setGroupCols("id")
            .setTimeCol("ts")
            .setPrecedingRows(2)
            .setFeatureCol("val")
            .setPredictionCol("pred")
            .setPredictionDetailCol("pred_detail");

    dataOp.link(outlierOp).print();

    StreamOperator.execute();

}

}
AlinkTestBase这个找不到，我就屏蔽了测试一下，然后发现结果好像不对。再就是把label那一列删掉了
