Abstract

A program was written to perform a linear least squares curve fitting on data. It includes facilities to report the usual statistics and digital plotter output. Seven types of curves are available for fitting the data. Other features of LILLY include provision of facilities for the selection of subsets in different symbols and separate curve fitting for these subsets. The program also provides a confidence region about the fitted line and the prediction interval for data points. Examples of the use of the program are described.

摘要

编写了一个程序，用于对数据进行线性最小二乘曲线拟合。它具备报告常用统计数据和数字绘图仪输出的功能。有七种类型的曲线可用于拟合数据。LILLY的其他特性包括提供以不同符号选择子集以及对这些子集进行单独曲线拟合的功能。该程序还提供关于拟合线的置信区域和数据点的预测区间。文中描述了该程序的使用示例。
