Analysis of Molecular Variance(AMOVA) is a method for studying molecular variation within a species. Electrophoresis, one of the most widely used methods for studying the structure of DNA, produces data of the form of 0s and 1s where 1 denotes the presence of a band and zero its absence, e. g. Sample Band A 0101... B 1000... C 0110... AMOVA works on such data to create a distance matrix between samples in order to measure the genetic structure of a population. In statistical terms, AMOVA is a testing procedure based on permutational analysis and involves few assumptions. 3, record 5, English, - analysis%20of%20molecular%20variance

A stochastic process is said to be strictly stationary if its probability distribution is completely independent of time. It is said to be stationary in the wide sense(or to the second order) if the mean and variance are independent of time. The statistics of samples drawn from a stationary process may vary due to sampling variability but not due to their size or their position in the population. 1, record 13, English, - stationary%20process

Un processus stochastique est dit stationnaire au sens strict si sa distribution de probabilité est totalement indépendante du temps. Il est dit stationnaire au sens large (ou au second ordre) si la moyenne et la variance sont indépendantes du temps. Les coefficients statistiques des échantillons tirés d'un processus stationnaire peuvent varier à cause de la variabilité d'échantillonnage mais non par suite de leur taille ou de leur position dans la population. 1, record 13, French, - processus%20stationnaire

Un proceso estocástico se considera estrictamente estacionario si su distribución de probabilidad es completamente independiente del tiempo. Se dice que es estacionario en un sentido amplio (o en un segundo orden), si la media y la varianza son independientes del tiempo. Los parámetros estadísticos de las muestras extraídas de un proceso estacionario, pueden variar debido a la variabilidad del muestreo, pero no debido a su tamaño o a su posición dentro de la población. 1, record 13, Spanish, - proceso%20estacionario

1. An unbiased estimator of the variance of a probability distribution obtained from a sample of n independent observations is obtained by dividing by n-1 the sum of the squares of the deviations of the observed values from the arithmetic mean of this sample. 2. The positive square root of the unbiased estimator of the variance is often used as an estimator of the standard deviation. However, it ought to be noted that this estimator is not unbiased. 3, record 16, English, - estimation%20of%20the%20variance%20of%20a%20population

a) Qualitatively : The closeness of agreement between individual results obtained with the same method on identical test material but under different conditions(different operators, different apparatus, different laboratories and/or different times). NOTE-The representative parameters of the dispersion of the population which may be associated to the results are qualified by the term "reproducibility". Example : Standard deviation of reproducibility, variance of reproducibility(...) b) Quantitatively : The value below which the absolute difference between two single test results on identical material obtained by operators in different laboratories, using the standardized test method, may be expected to lie with specified probability.
