误差 Errors and residuals(重定向自Statistical error)
误差(errors)是实验科学术语。指测量结果偏离真值的程度。对任何一个物理量进行的测量都不可能得出一个绝对准确的数值,即使使用测量技术所能达到的最完善的方法,测出的数值也和真实值存在差异,这种测量值和真实值的差异称为误差。数值计算分为绝对误差和相对误差。也可以根据误差来源分为系统误差(又称可定误差、已定误差)、随机误差(又称机会误差、未定误差)和毛误差(又称粗差)。

Errors and residuals 误差(重定向自Statistical error)
![]() In statistics and optimization, errors and residuals are two closely related and easily confused measures of the deviation of an observed value of an element of a statistical sample from its "theoretical value". The error (or disturbance) of an observed value is the deviation of the observed value from the (unobservable) true value of a quantity of interest (for example, a population mean), and the residual of an observed value is the difference between the observed value and the estimated value of the quantity of interest (for example, a sample mean). The distinction is most important in regression analysis, where it leads to the concept of studentized residuals. |
