A lognormal error is usually assumed in the traditional stock–recruitment(SR) analysis.... a positive bias results when [a] SR model with [a] lognormal error is used for fish recruitment prediction. Not only is this bias exponentially dependent on the structure of the model' s residual variance and the historical SR data, it is also dependent on the specific value of spawner biomass used.... a bias correction that is asymptotically unbiased with a finite-sample biasthat is practically zero [is then derived]. Data from two Pacific salmon populations, southeast Alaska pink salmon... and Chilko Lake sockeye salmon... are used to demonstrate this approach. The results show that the relative bias is about 10% for a spawning biomass within the historical range and that the bias is substantial outside that data range. However, with the proposed bias correction, the bias is negligible both within(<0. 1%) and outside of(<0. 3%) the data range. 2, record 1, English, - bias%20correction

The idea of giving a weight to the particles, in proportion to their likely contribution to the result being sought. This should be associated with the Russian roulette consisting of “killing” particles whose weight is too low, with a probability that is proportional to the weight, and the “duplication” or “splitting” of particles that are too heavy. It can also be sometimes of interest to replace absorptions (capture and fission) by weight charges, without stopping the particles … 3, record 3, English, - splitting%20technique

… the optimization and quantification of particle splitting [is] a variance reduction technique that decreases the variance of a run, [sigma], or its relative error, R, while increasing its computational time, [tau]. This splitting technique is described in several papers, books, and reports. Geometry splitting associated with Russian roulette is one of the most widely used variance reduction techniques in Monte Carlo codes. When used effectively(i. e. splitting a volume in the right number of layers), this method causes a net increase in the figure of merit, FOM … [In a given example of splitting technique], an incident neutron n0 of weight W is split at the boundary crossing into two identical neutrons na and nb(same energy, direction) having half the weight of n0. The number of split particles and their weight are given by the ratio of weight associated with each volume of the problem. 1, record 3, English, - splitting%20technique

Splitting. Dans les calculs de propagation profonde, les effets d’angle solide font en sorte que la plupart des particules ratent la cible (qui, en général, possède des dimensions assez petites par rapport à celles de la source et aux distances en jeu) : les temps de calcul risquent alors de devenir prohibitifs. La technique du splitting, qui consiste à dédoubler en fragments de poids réduit chaque particule franchissant une surface donnée dans la direction de la cible, permet de conserver partiellement l’information de la composante de vitesse utile. Après génération, chaque fragment est suivi individuellement et peut, à son tour, subir des fragmentations. L’idée est donc de multiplier le nombre de particules, quitte à en diminuer le poids, aux environs de la cible. Chaque fragment traversant la cible fournira, alors, une contribution — réduite — à la fonction réponse recherchée. Le procédé complémentaire, la roulette russe, est appliqué aux échantillons, ou fragments d’échantillons, traversant une surface de splitting dans la mauvaise direction par rapport à la cible : une fois sur deux, on annihile la particule et l’autre fois on continue à la suivre avec un poids multiplié par deux. On génère ainsi une population éparse de particules lourdes loin de la cible. 1, record 3, French, - technique%20du%20splitting

When reliability is measured by the test-retest method, a coefficient of stability is obtained. This reliability coefficient measures error variance due to temporal variations in characteristics of the examinee, as well as variation in conditions of test administration.... the interval between tests should be at least several days so that the student's memory of his answers does not spuriously increase the consistency of scores. However, the time interval should not exceed two or three weeks because we are trying to measure stability of student performance on the test, than the stability of the interest, ability or personality trait measured. 1, record 13, English, - test%2Dretest%20method

Méthode test-retest. On applique le même test aux mêmes sujets après un certain intervalle de temps. La corrélation entre les deux séries de notes est un coefficient de fidélité particulier appelé coefficient de stabilité; il mesure la stabilité de la note d'un sujet pendant un certain intervalle de temps. En général, plus l'intervalle est important, plus la fidélité que l'on apprécie ainsi est faible. 3, record 13, French, - m%C3%A9thode%20test%2Dretest
