是什么启发了这个愿望清单请求？
目的是过滤数据并删除异常值，以便排除具有许多缺陷的晶圆并确定标准。数据遵循泊松分布
请描述您希望看到的新的或改进的功能或解决方案。
他们希望使用迭代 3 sigmas 方法来检测异常值。
这意味着：
- 测量样本的平均值和标准差。
- 删除高于平均值加上 3 个标准差的样本。
- 从步骤1开始重复，总共3次。
如果提供此新功能，对您和/或其他用户有何价值？
这是外部客户请求吗？

是否存在具有此功能或解决方案且值得我们了解的竞争性软件包？
不知道
这是否会影响客户的续约、扩展或采用？如果我们不解决这个问题，是否会使账户面临风险？

嗨@flo_kuster ，
下面的内容是否可以同时适应客户需求？它只是使用 JSL 中的 std dev() 函数对定义的标准偏差进行一次传递。
