von Bertalanffy鱼类生长曲线两种常用拟合方法的一致性讨论

本文指出,拟合von Bertalanffy鱼类特殊生长曲线常用的Tomlinson-Abramson方法与Allen方法在参数点估计和区间估计方面没有什么本质的不同;以拟庸鲽(Pleuronectes platessa L)雌鱼的生长为例,对其参数估计量性质作模拟研究的结果表明;各参数估计量的非线性性态是显著的。

Discussion on the Consistence of Two Commonly Used Methods for Fitting Fish Growth Curve of von Bertalanffy

This paper shows that there exists no essential distinction between the two commonly used methods i. e., Tomlinson-Abramson method and Allen method for fitting special fish growth curve of yon Bertalanffy with regard to the methods of point and interval estimations of parameters. Results of a simulation study on female plaice (Pleuronectes platessa L.) for the properties of parameter estimator determined by the two methods indicate that their non-linear property is significant.
