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.
