分别使用91、57、94和102种化合物生成OV-101（R = 0.997）、DB-1（R = 0.998）、DB-5（R = 0.997）和DB-Wax（R = 0.982）的气相色谱保留指数的高质量回归模型。使用二阶方程生成模型，该方程包括利用两个容易获得的变量（沸点和辛醇-水系数的对数）的叉积。此外，提出了一种确定离群值数据的方法（GOodner离群值确定（GOOD）方法），该方法是几种离群值测试的组合，并且不太容易丢弃合法数据。由Elsevier Ltd.代表瑞士食品科学与技术协会出版。
High-quality regression models of gas chromatographic retention indices were generated for OV-101 (R = 0.997), DB-1 (R = 0.998), DB-5 (R = 0.997), and DB-Wax (R = 0.982) using 91, 57, 94, and 102 compounds, respectively. The models were generated using a second-order equation including the cross product utilizing two easily obtained variables, boiling point and the log octanol-water coefficient. Additionally, a method for determining outlier data (the GOodner Outlier Determination (GOOD) method) is presented, which is a combination of several outlier tests and is less prone to discarding legitimate data.
