| 摘 要： | 本文用Logistic模型配合Monte Cario方法模拟的30个家禽生长资料,以比较Logis-tic模型参数估计的最小一乘法、最小二乘法和minx~2法,以及线性化方法。结果表明:最小二乘法(LS)和最小一乘法结果相当,均优于ininx~2方法;参数估计的线性化方法结果较差,以改良三点法效果较好。

| Abstract: | In the paper,Logistic model was used to fit 30 poultry growth data seus simulated by Monte Carlo method in order to compare its parameter estimation methods. The results were as follows;thc results of both LS and least absolute deviations methods were rather approximative, both of them were better than that of min x2method;the results of the lineared methods were relatively poor,but that of the improved three points method were relatively better. |
