Formally, this model belongs to the general class of state space models. The specifics of SSA is in the facts that parameter estimation is a problem of secondary importance in SSA and the data analysis procedures in SSA are nonlinear as they are based on the SVD of either trajectory or lag-covariance matrix.
Missing at random (MAR) occurs when the missingness is not random, but where missingness can be fully accounted for by variables where there is complete information. [7] Since MAR is an assumption that is impossible to verify statistically, we must rely on its substantive reasonableness. [ 8 ]

Model checkers like FizzBee uses Starlark/Python as the modeling language. TLA+: General-purpose specification language based on the Temporal Logic of Actions, originally used for distributed and concurrent systems. The language for the specifications and their properties is the same.
STANAG 4355 – The Modified Point Mass and Five Degrees of Freedom Trajectory Model, an element of military strategy, is a NATO Standardization Agreement for surface to surface exterior ballistic modelling in support of Artillery, mortar and rocket systems.
They are a popular alternative to the likelihood-based generalized linear mixed model which is more at risk for consistency loss at variance structure specification. [5] The trade-off of variance-structure misspecification and consistent regression coefficient estimates is loss of efficiency, yielding inflated Wald test p-values as a result of ...
The Toolkit for Conceptual Modeling (TCM) is a collection of software tools to present specifications of software systems in the form of diagrams, tables, trees, and the like. TCM offers editors for techniques used in Structured Analysis as well as editors for object-oriented (UML) techniques.
