von Bertalanffy鱼类生长曲线两种常用拟合方法的一致性讨论

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

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。

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.
