For the music theory concept of "modes", see Mode (music). In statistics, the mode is the value that appears most often in a set of data values. [ 1 ] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmaxxi P (X = xi) ). In other words, it is the value that is ...
v. t. e. A descriptive statistic (in the count noun sense) is a summary statistic that quantitatively describes or summarizes features from a collection of information, [ 1] while descriptive statistics (in the mass noun sense) is the process of using and analysing those statistics. Descriptive statistics is distinguished from inferential ...
Robust statistics are statistics that maintain their properties even if the underlying distributional assumptions are incorrect. Robust statistical methods have been developed for many common problems, such as estimating location, scale, and regression parameters. One motivation is to produce statistical methods that are not unduly affected by ...
Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. [ 1] Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population.
a measure of statistical dispersion like the standard mean absolute deviation. a measure of the shape of the distribution like skewness or kurtosis. if more than one variable is measured, a measure of statistical dependence such as a correlation coefficient. A common collection of order statistics used as summary statistics are the five-number ...
In mathematical terms, a statistical model is a pair (,), where is the set of possible observations, i.e. the sample space, and is a set of probability distributions on . [3]
French Statistical Society. The French Statistical Society (in French, Société française de statistique, SFdS) is a French learned society founded in 1997 [ 1][ 2][ 3] specializing in statistics. Its vocation is to promote the use of statistics, enhance its public understanding, and encourage associated methodological developments.
It 2D hydrodynamics module, TELEMAC-2D, solves the so-called shallow water equations, also known as the Saint Venant equations. TELEMAC-2D solves the Saint-Venant equations using the finite-element or finite-volume method and a computation mesh of triangular elements. It can perform simulations in transient and permanent conditions.
