La capacité porteuse (aussi appelée capacité de charge, capacité limite, capacité de soutien, capacité biotique ainsi que capacité de support au Québec et carrying capacity en anglais) en écologie est la taille maximale de la population d’un organisme qu’un milieu donné peut supporter.
Regression validationIn statistics, regression validation is the process of deciding whether the numerical results quantifying hypothesized relationships between variables, obtained from regression analysis, are acceptable as descriptions of the data. The validation process can involve analyzing the goodness of fit of the regression, analyzing whether the regression residuals are random, and checking whether the model's predictive performance deteriorates substantially when applied to data that were not used in model estimation.
Space mappingThe space mapping methodology for modeling and design optimization of engineering systems was first discovered by John Bandler in 1993. It uses relevant existing knowledge to speed up model generation and design optimization of a system. The knowledge is updated with new validation information from the system when available. The space mapping methodology employs a "quasi-global" formulation that intelligently links companion "coarse" (ideal or low-fidelity) and "fine" (practical or high-fidelity) models of different complexities.
Verification and validationVerification and validation (also abbreviated as V&V) are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose. These are critical components of a quality management system such as ISO 9000. The words "verification" and "validation" are sometimes preceded with "independent", indicating that the verification and validation is to be performed by a disinterested third party.
Latent class modelIn statistics, a latent class model (LCM) relates a set of observed (usually discrete) multivariate variables to a set of latent variables. It is a type of latent variable model. It is called a latent class model because the latent variable is discrete. A class is characterized by a pattern of conditional probabilities that indicate the chance that variables take on certain values. Latent class analysis (LCA) is a subset of structural equation modeling, used to find groups or subtypes of cases in multivariate categorical data.
Conflits environnementauxUn conflit environnemental est un conflit causé par la dégradation de l'environnement dans le cadre d'une mauvaise gestion des ressources environnementales. Généralement, plusieurs parties sont impliquées, y compris les défenseurs de l'environnement qui veulent protéger l'environnement, et ceux qui réclament ou gèrent mal l'environnement pour autre chose, généralement l'industrie extractive.
