Choosing A Procedure

 

使用下拉菜单、过程搜索或类别树,查找示例大小过程很容易。观看一段简短的视频,学习如何选择你想要的程序。

 
Enter The Values
 

sample size过程工具易于使用,并且对于每个选项都有内置的帮助消息。

 

放大信息图以查看传递方法的描述,这有助于您在示例大小过程工具中输入适当的值。您还可以观看本视频,以了解在PASS中使用过程窗口的示例。

 
Obtaining A Sample Size In PASS
 
在PASS中,您可以在几个短步骤中估计统计测试或置信区间的样品量。如果你在任何一个步骤中需要指导,PASS有优秀的文档,有免费的培训视频,你可以联系我们的统计博士团队。

Sample Size & Power

 

PASS软件为超过920个统计测试和置信区间场景提供了样本量工具—是任何其他样本量软件的两倍多。每个工具都经过已发表的文章和/或文本的仔细验证。

PASS提供完整的集成文档和博士统计学家支持。

PASS已经经过了20多年的微调,现在是临床试验、制药和其他医学研究的首选样本量软件。它还成为所有其他需要样本量计算或评价的领域的支柱。

 
Ready to Use Output

 

当运行一个PASS过程时,在输出窗口中显示示例大小的结果和相应的图。可以单击示例大小或功率曲线,以显示在单独的窗口中查看或保存。
 
输出导航树可以很容易地导航输出。输出的格式使其易于查看、复制和粘贴,或保存。可以将多个输出运行发送到输出库以保存或比较样本大小分析。
