k****r 发帖数: 6 | 1 请问在分析数据时,LSD test 和 Duncan 的区别?我用的是SAS。我用同样的数据发现
duncan的significant groups比LSD的要少,而且适合用于多个trt的实验。
我wiki上看到:
Duncan's MRT is especially protective against false negative (Type II) error
at the expense of having a greater risk of making false positive (Type I)
errors. Duncan's test is commonly used in agronomy and other agricultural
research.
TypeI错误应该使groups变多,TypeII错误使groups变少,Duncan‘s test减少typeII
错误,但为什么运行同样数据的时候,groups变少了。没想明白是怎么回事? | k****r 发帖数: 6 | 2 请问在分析数据时,LSD test 和 Duncan 的区别?我用的是SAS。我用同样的数据发现
