SAS is a powerful statistical package but it does not cover all analyses that a user may require particularly in a specialized area such as biological assay. A SAS program SLOPE has been developed for the analysis of biological assays in complete randomization based on the slope ratio method. The program is capable of checking the statistical validity of an assay and estimating the potencies of test preparations relative to a standard. It calculates potencies and their corresponding confidence intervals for a group of bioassays where each assay has equal number of preparations. It also allows the user to produce scatter plots of response by dose.
SAS是一个功能强大的统计软件包，但它并不能涵盖用户可能需要的所有分析，特别是在生物测定等专业领域。已经开发了一个名为SLOPE的SAS程序，用于基于斜率比法对完全随机化的生物测定进行分析。该程序能够检查测定的统计有效性，并估计测试制剂相对于标准品的效价。它可以计算一组生物测定的效价及其相应的置信区间，其中每个测定的制剂数量相等。它还允许用户生成响应与剂量的散点图。
