Error analysis (mathematics) : ウィキペディア英語版 | Error analysis (mathematics) In mathematics, error analysis is the study of kind and quantity of error, or uncertainty, that may be present in the solution to a problem. This issue is particularly prominent in applied areas such as numerical analysis and statistics. == Error analysis in numerical modeling ==
In numerical simulation or modeling of real systems, error analysis is concerned with the changes in the output of the model as the parameters to the model vary about a mean. For instance, in a system modeled as a function of two variables . Error analysis deals with the propagation of the numerical errors in and (around mean values and ) to error in (around a mean ). In numerical analysis, error analysis comprises both forward error analysis and backward error analysis.
