Say I have $x_{true} = 0$ and $x_{test}$. If I define relative error as: $\text{relative error} = \frac{x_{true}-x_{test}}{x_{true}}$ Then the relative error is always undefined. If instead I use the definition: $\text{relative error} = \frac{x_{true}-x_{test}}{x_{test}}$ Then the relative error is always 100%. Both methods seem useless. Is there another alternative? statistics share|cite|improve this question asked Feb 15 '14 at 22:41 okj 9461818 1 you need a maximum for that.. –Seyhmus Güngören Feb 15 '14 at 23:06 1 Simple and interesting question, indeed. Could you tell in which context you face this situation ? Depending on your answer, there are possible alternatives. –Claude Leibovici Feb 16 '14 at 6:24 1 @ClaudeLeibovici: I am doing a parameter estimation problem. I know the true parameter value ($x_{true}$), and I have simulation data from which I infer an estimate of the parameter ($x_{test}$). I want to quantify the error, and it seems that for my particular ca

not necessary that one should find relative and % error for very small values. They are important when your actual(exact) value is very large. Mar 7, 2014 Geen Paul V · Tata Consultancy Services Limited Sir, http://math.stackexchange.com/questions/677852/how-to-calculate-relative-error-when-true-value-is-zero I am working on Finite Element Analysis for an aerospace company in USA. The Company Spoke wants to get ma computed values sometimes validated by hand calculation. And sometimes the actual stress value may be zero. but the numerical analysis value varies by less than 1. And I was wondering how to make it in percentage. ! Mar 7, 2014 Hanno Krieger · retired from Justus-Liebig-Universität Gießen I try to follow. If you https://www.researchgate.net/post/How_to_calculate_percentage_error_when_one_value_is_zero02 get experimental results which allow a statistical analysis (gauss or poisson distributions) you use the established methods of error calculation. If you have only a small number of results it´s without any sense to calculate average values or medians etc. So if you spent a little bit more information (possibly with an example) I could find a tip. Mar 7, 2014 Hanno Krieger · retired from Justus-Liebig-Universität Gießen Like to add a remark. You can calculate errors not before you define a reference value. Thats what I´m missing most in your question. Mar 7, 2014 Joseph Dubrovkin · Western Galilee College You can calculate lim(deltaX/X) when X->0 using l'Hôpital's rule or graphically. The relative error is important when X->0. E.g., detection limit. Mar 8, 2014 Luca Dimiccoli · Vrije Universiteit Brussel Notice that deltaX does not satisfy all the hypotheses of the Hopital's rule. Moreover, the limit that is suggested does not exist. Mar 8, 2014 Manuel Antonio Borregales Reverón · University of Bergen I think the key is the value of references that you can use, for example I try to simulate a sum of forces acting on an object. In my study the summation of forces must be zero, but in the simulations obtain values of 0.01 [Nw]. The forces applied to the body

| Scientific Calculator | Statistics Calculator In the real world, the data measured or used is normally different from the true value. The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. Normally people use absolute error, relative error, and percent error to represent such discrepancy: absolute error = |Vtrue - Vused| relative error = |(Vtrue - Vused)/Vtrue| (if Vtrue is not zero) percent error = |(Vtrue - Vused)/Vtrue| X 100 (if Vtrue is not zero) Where: Vtrue is the true value Vused is the value used The definitions above are based on the fact that the true values are known. In many situations, the true values are unknown. If so, people use the standard deviation to represent the error. Please check the standard deviation calculator.
