PASS 样本大小分析软件
样本大小和功能
PASS软件为超过740个统计测试和置信区间场景提供样本大小工具-比任何其他样本大小软件工具多一倍以上。每个工具都经过了公开的文章和/或文本的仔细验证。
PASS有完整的文档和博士统计学家的支持。
经过了20多年的精心调整，PASS已成为试验、制药和其他研究领域的样本软件选择。它也成为所有其他需要进行样本量的计算或评估的领域的支柱。
在PASS中获取样本大小
在PASS中，您可以在几个短的步骤中估计一个统计测试或置信区间的样本大小。如果您在任何步骤中都需要，那么可以通过PASS完整的文档，您也可以联系我们的博士统计学家团队获得帮助。
选择一个进程
使用下拉菜单、过程搜索或类别树，查找样本大小过程是很容易的。
Choosing A Procedure
Finding the right analysis or graphics procedure is easy using the drop-down menu, the procedure search, or the category tree. Watch a short video to learn how to select your desired procedure in NCSS.
