In the area of system identification, a dynamical system is structurally identifiable if it is possible to infer its unknown parameters by measuring its output over time. . This problem arises in many branch of applied mathematics, since dynamical systems (such as the ones described by ordinary differential equations) are commonly utilized to model physical processes and these models contain ...
Causal interpretations of SE models are the clearest and most understandable but those interpretations will be fallacious/wrong if the model’s structure does not correspond to the world’s causal structure. Consequently, interpretation should address the overall status and structure of the model, not merely the model’s estimated coefficients.
Stochastic frontier analysis has examined also "cost" and "profit" efficiency. [2] The "cost frontier" approach attempts to measure how far from full-cost minimization (i.e. cost-efficiency) is the firm. Modeling-wise, the non-negative cost-inefficiency component is added rather than subtracted in the stochastic specification.
This is a standalone application, which is operated outside the STAAD.Pro environment, but requires a model and results data from a suitable analysis. The model should typically be formed from beams and columns (plates are currently not supported). RCDC can be used to design the following objects: Pile Caps, Footings, Columns and walls, Beams ...
Structural analysis is a branch of solid mechanics which uses simplified models for solids like bars, beams and shells for engineering decision making. Its main objective is to determine the effect of loads on physical structures and their components. In contrast to theory of elasticity, the models used in structural analysis are often ...
Structural model of the psyche, a Freudian model of psychology; Structural equation modeling, mathematical, statistical and computer algorithm models that fit constructs to data; Structural model (software), a diagram that the describes the static structure of a computer program; Marginal structural model, a class of statistical models used in ...
Among several technologies pioneered by SDRC, it was one of the first companies to introduce a Product Lifecycle Management (PLM) solution, as a result of its joint venture with Control Data. The product, Metaphase, eventually became the sole property of SDRC.
A structural model often involves sequential decision-making under uncertainty or strategic environments where beliefs about other agents' actions matter. Parameters of such models are estimated not with regression analysis but non-linear techniques such as generalized method of moments, maximum likelihood, and indirect inference. The reduced ...
