数据不完整情况下的曲线拟合问题

How to Fit A Curve on the Occasion of Incomplet Data

本文针对统计断裂力学中数据不完整(例如缺少数值小的数据)情况下如何进行曲线拟合的问题,提出了一种解决方法,该方法先用部分样本观察值估计分布参数,然后以外推的方式进行分布曲线的拟合.

Thie paper aims at how to fit a curve on the occasion of incomplete data (such as the lack of smaller value data) in statistical fracture mechanics.A method , in which we first use a part of observations to estimate the values of the parameters of the parent population and then fit a curve in the extensional way, is presented.
