An extended analysis of variance is presented for a multiexponential curve fitting procedure, known as 'curve stripping', 'curve peeling', or 'successive subtraction'. In addition to the standard, single variable curves, this analysis includes the two dimensional multiexponential surface analysis. The calculations take into account features required by the graphical user interface that was specifically designed to facilitate the fitting process. The evaluation of the goodness of fit includes an F test (to evaluate the number of components needed to fit the data), and correlation coefficients (to evaluate individual parameters).
本文针对一种多指数曲线拟合程序（称为“曲线剥离”“曲线剥除”或“逐次减法”）给出了扩展方差分析。除了标准的单变量曲线外，该分析还包括二维多指数曲面分析。计算考虑了专门为便于拟合过程而设计的图形用户界面所需的特性。拟合优度的评估包括F检验（用于评估拟合数据所需的成分数量）和相关系数（用于评估各个参数）。
