单侧t检验
[size=150:9134f]
编程不知道如何处理,
但是好象在analyst中做t检验的时候可以设定备择假设.
这应该可以满足要求吧
通常备择假设型如:mean^=5.
你选择型如:mean>5
[/size:9134f]
[quote:9134f]You can choose one of three alternative hypotheses. The default is that the difference between the means is not equal to the specified difference, which is the two-sided alternative. The one-sided alternatives are that the difference is greater than, or less than, the difference specified in the null hypothesis.[/quote:9134f] |
