Record 2 2001-01-31

English

Subject field(s)
  • Mathematical Geography
  • Remote Sensing
DEF

A measure of the variability of measurements about their true values.

OBS

The RMS error is estimated by taking sample measurements and comparing them to their true values. These differences are then squared and summed. The sum is then divided by the number of measurements to achieve a mean square deviation. The square root of the mean square deviation is then taken to produce a characteristic error measure in the same units as the original measurements. The RMS error is directly comparable to the concept of a standard deviation.

OBS

root-mean-square error; RMS error: terms and definition provided by the Canadian Hydrographic Service.

DEF

Mesure de la variabilité de mesures par rapport à la valeur vraie.

OBS

L'erreur-type est estimée en effectuant des mesures et en les comparant à la valeur vraie. Les différences sont mises au carré et additionnées. Cette somme est ensuite divisée par le nombre de mesures effectuées pour obtenir le carré de la moyenne quadratique. En extrayant la racine carrée du carré de la moyenne quadratique, l'on obtient une mesure caractéristique de l'erreur dans les mêmes unités que les mesures d'origine. Le concept d'erreur quadratique moyenne (erreur-type) est directement comparable à celui de l'écart-type.

Record 3 1998-07-30

English

Subject field(s)
  • Statistics
DEF

The square root of the mean square error [derived from variate values]

OBS

mean square error: ... the average of the squared distance between the estimate and the parameter.

OBS

A measure of the error to which one is exposed by the use of an estimator, which is given by the expected value of the squared difference between the estimator and a (theoretically) correct value. For unbiased estimators, the mean square error equals the variance.

French

Domaine(s)
  • Statistique
CONT

L'erreur type est l'écart type d'une distribution d'échantillonnage d'une mesure obtenue à partir de calculs effectués sur un échantillon.
