一、词典解释点此查看variance的详细内容

e.g. ...the variances in the stock price.
股票价格的变化
e.g. ...total revenuevariance.
总收入的差异
二、网络解释
1. 方差：16 方差(variance)是一组数据中各变量与其均值离差平方的平均数,方差的算术平方根叫标准差(standard deviation). 方差与标准差是反映数值型数据离散程度的主要的也是常用的方法,是描述数据分布特征的重要的统计量.
2. 变异数：心率变异性分析则是通过测量连续正常的QRS波群周期之间的变化(beat to fluctuation)变异数(Variance),从而反应心率的变化. 它不同于常用的以时间为单位的平均心率变化指标(如最大心率或最小心率等),HRV的大小并不反映心率的快慢.
3. 差异：除此之外,Breiman [Bre96a] 还从偏向(bias)和差异(variance)的角度对泛化误差进行了分析. 他指出,不稳定预测函数的偏向较小、差异较大,Bagging正是通过减小差异来减小泛化误差的. 在此之后,
