A range of values below and above the point estimate that has a given probability of including the true value of a given parameter, such as a treatment effect.  3, record 1, English, - confidence%20interval

Record number: 1, Textual support number: 1 OBS

The confidence interval is the area of uncertainty for the estimating of a parameter. The use of this interval reflects the fact that a study provides one estimate of a parameter, out of the many estimates that would be possible if the study were repeated several times. If an X% CI is constructed for each repetition, X% of the intervals will contain the true value of the parameter. Investigators typically use confidence intervals of 90%, 95% or 99%. Thus, a 95% confidence interval indicates that there is a 95% probability that the confidence interval calculated from a particular study includes the true value of the parameter. If the interval includes a null value(a difference in means of 0, an odds ratio or a relative risk of 1, or a correlation coefficient of 0, for example), the null hypothesis cannot be rejected. A narrow confidence interval around a point estimate indicates a more precise estimate than a wide confidence interval.  3, record 1, English, - confidence%20interval

The validity of the confidence interval depends upon knowledge of the underlying distribution of the population or assumptions about behavior of the sampling distribution.  4, record 1, English, - confidence%20interval

L’intervalle de confiance représente la zone d’incertitude quant à l’estimation d’un paramètre. L’utilisation de cet intervalle tient compte du fait qu’une étude fournit une estimation d’un paramètre parmi les nombreuses estimations qui seraient possibles si l’étude était répétée plusieurs fois. Si un IC à X % est construit pour chacune des répétitions, X % des intervalles contiendront la vraie valeur du paramètre. Les chercheurs utilisent habituellement des intervalles de confiance à 90, 95 ou 99 %. Ainsi, un intervalle de confiance à 95 % indique une probabilité de 95 % que l’intervalle de confiance calculé à partir d’une étude donnée contienne la vraie valeur du paramètre. Si l’intervalle comprend une valeur nulle (une différence de moyennes de 0, un rapport des cotes ou un risque relatif de 1, un coefficient de corrélation de 0, par exemple), l’hypothèse nulle ne peut être rejetée. Un intervalle de confiance étroit autour de l'estimation ponctuelle indique une estimation plus précise qu'un intervalle de confiance large.  3, record 1, French, - intervalle%20de%20confiance

The sodium adsorption ratio(SAR) is used to estimate what the exchangeable sodium percentage of a soil is, or what it is likely to become, if the water that comprises the sampled soil water is used for irrigation for long periods of time. The reason for using the SAR is that it has a good correlation to the exchangeable sodium percentage(ESP) and is much easier to calculate exactly or to estimate from a few simple analyses than is the ESP.  3, record 3, English, - sodium%20adsorption%20ratio

Planimetric control. Segmentation is sometimes a ground step for correlation which approximates regions by plans, thus we have studied a way to control in 2D the planimetric differences between a reference and a segmentation outline. Various distances have been used for this purpose : Haussdorf distance from segmentation boundaries to reference ones seem to be the most appropriate. A recovering surface quality estimator has been tried and we have computed the ratio between intersection and union with respect to the both areas. This method will be used on many test sites.  1, record 4, English, - planimetric%20control

Contrôle planimétrique. La segmentation étant dans certains cas à l'origine d'algorithmes de reconstruction 3D (corrélation par masques adaptatifs ou approximation des surfaces par des plans), nous avons étudié la qualification d'un contour 2D issu d'une segmentation pour savoir si les contours des régions collent au plus près d'un contour de référence. Diverses distances ont été utilisées pour quantifier cette proximité par rapport à la référence ainsi qu'un estimateur de qualité de recouvrement entre les deux surfaces (rapport de l'intersection sur la réunion). Cette méthode va être testée sur divers chantiers.  1, record 4, French, - contr%C3%B4le%20planim%C3%A9trique
