One is to compare the sample mean and the sample variance.

当样本均值大于样本方差时，认为是服从二项分布；

However, these methods are estimated according to sample variance and covariance estimators of returns.

然而，这些方法都是根据样本的变异数或报酬的共变异数估算的估计值。

The Markov chain Monte Carlo move plus Gaussian white noise is used in sample variance and breeding, and the MH sampling algorithm is used to select sample, too.

使用了马尔可夫链蒙特卡罗移动加高斯白噪声做样本变异繁殖并使用快速MH 抽样算法选取样本。

Populations, random samples. Sample statistics, moments of the sample mean and variance.

母体， 随机样本。 样本统计， 样本平均数和变异数的动差。

This components of parameter variance depends on the sample size.

参数方差的这一组成部分依赖于样本容量。
