5.3.2修补异常值

通过直接删除的方式处理异常值，虽然是最直接方法的方法，但是会减少数据样本，因此在数据集小的情况下，减少数据样本会对结果产生影响；在含有较多异常值的数据集中，大量的删除异常值也会对结果产生影响。因此，当异常值没有可研究性的情况下，应该对这些异常值进行修补处理。 修补异常值的方式主要有两种，即改异常值和替换异常值。

1.案例介绍

通过Kettle工具，替换和修改数据表interpolation_data中的异常值。

2.数据准备

现在有一份500人的身高调查数据表interpolation_data，其中包括id、Gender和Height字段，具体数据内容如图所示（注：这里只截取了部分人的数据）。

 3.具体步骤

（1）打开Kettle工具，创建转换

通过使用Kettle工具，创建一个转换fill_unusual_value，并添加“表输入”控件、“过滤记录”控件、“空操作（什么也不做）”控件、“设置值为NULL”控件、“合并记录”控件、“替换NULL值”控件、字段选择控件以及Hop跳连接线。

（2）配置表输入控件 

双击“表输入”控件，进入“表输入”配置界面，单击【新建】按钮，配置数据库连接。

 在SQL框中编写查询数据表interpolation_data的SQL语句，然后单击【预览】按钮，查看数据表interpolation_data的数据是否成功从MySQL数据库中抽取到表输入流中。

注：数据表interpolation_data要提前建立，以下代码仅供参考：

（3）配置过滤记录控件

双击“过滤记录”控件，进入“过滤记录”配置界面，在“条件”处设置过滤的条件，即设置Height字段的取值范围（[114-226]），从而判断数据表中的每个数据是否为异常值。

异常数据python 异常数据的处理方法_开发语言_05

在“发送true数据给步骤：”处的下拉框中选择“空操作（什么也不做）2”，在“发送false数据给步骤：”处的下拉框中选择“空操作（什么也不做）”。

（4）预览“空操作（什么也不做）”控件中的数据 

选中“空操作（什么也不做）”控件，然后单击转换工作区顶部的 按钮，预览“空操作（什么也不做）”控件中的数据，id为15的这条数据，Height字段为260，260不在非异常值范围[114，226]内，因此该条数据为异常数据。

（5）配置过滤记录控件 

双击“设置值为NULL”控件，进入“设置值为NULL”界面；在“字段”处添加要设为NULL值的字段名称和值。

 （6）配置合并记录控件

双击“合并记录”控件，进入“合并行（比较）”界面，在“旧数据源：”处的下拉框选择“设置为NULL值”，“新数据源：”处的下拉框选择“空操作（什么也不做）2”；在“匹配的关键字：”处，添加关键字段，即id。

（7）配置替换NULL值控件 

双击“替换NULL值”控件，进入“替换NULL值”界面，勾选“选择字段”处的复选框，并在“字段”框添加字段为Hight，值替换为170。

（8）配置字段选择控件 

双击“字段选择”控件，进入“选择/改名值”界面，在“移除”选项卡处添加要移除的字段名称，这里移除的是字段flagfield。
