Что (кто) такое constrained randomization - определение

STATISTICAL METHOD IN GENETIC EPIDEMIOLOGY
Mendelian randomisation; Mendelian randomization analysis; Mendelian Randomization
  • Directed acyclic graph traditionally used to represent the Mendelian randomization framework and its core assumptions. <math>Z</math> is the genetic variants, <math>X</math> is the exposure, <math>Y</math> is the outcome of interest, and <math>U</math> are possible confounders.
  • Gregor Mendel. The term Mendelian randomization was termed because the random assignment of genetic variants from parents to offspring is fundamental to the method.

Mendelian randomization         
In epidemiology, Mendelian randomization (commonly abbreviated to MR) is a method using measured variation in genes to interrogate the causal effect of an exposure on an outcome. Under key assumptions (see below), the design reduces both reverse causation and confounding, which often substantially impede or mislead the interpretation of results from epidemiological studies.
Degree-preserving randomization         
Degree Preserving Randomization
Degree Preserving Randomization is a technique used in Network Science that aims to assess whether or not variations observed in a given graph could simply be an artifact of the graph's inherent structural properties rather than properties unique to the nodes, in an observed network.
Constrained comics         
Constrained comic
Constrained comics is a form of comics that places some fundamental constraint on form beyond those inherent to the medium. By adding a constraint, the artist is attempting to produce original art within tightly defined boundaries.
Constrained optimization         
IN FINANCE, LINEAR PROGRAMMING, ECONOMICS AND COST MODELING
Constrained optimization problem; Constraint optimization; Maratos effect; Soft constraint; Hard constraint; Algorithms for solving constrained optimization problems; Methods for solving constrained optimization problems; Constrained minimisation; Constrained minimization
In mathematical optimization, constrained optimization (in some contexts called constraint optimization) is the process of optimizing an objective function with respect to some variables in the presence of constraints on those variables. The objective function is either a cost function or energy function, which is to be minimized, or a reward function or utility function, which is to be maximized.
Constrained geometry complex         
  • A constrained geometry organotitanium complex in the (inactive) chloride form.
KIND OF CATALYST
Constrained geometry catalyst; Constrained geometry catalysts; Constrained geometry complexes
In organometallic chemistry, a "constrained geometry complex" (CGC) is a kind of catalyst used for the production of polyolefins such as polyethylene and polypropylene.Klosin, J.

[k?lt]
¦ noun
1. a member of a group of peoples inhabiting much of Europe and Asia Minor in pre-Roman times.
2. a native of a modern nation or region in which a Celtic language is (or was until recently) spoken.
Origin
from L. Celtae (plural), from Gk Keltoi.
Path-constrained rendezvous         
ISSUE OF MANEUVERING IN OUTER SPACE WITHOUT ENCOUNTERING OBSTACLES
Path-constrained Rendezvous
Path-constrained rendezvous is the process of moving an orbiting object from its current position to a desired position and velocity, in such a way that no obstacles are contacted along the way. It is a more constrained instance of the general problem of orbital rendezvous.
P-constrained group         
A FINITE GROUP
P-constrained; P-constraint
In mathematics, a p-constrained group is a finite group resembling the centralizer of an element of prime order p in a group of Lie type over a finite field of characteristic p. They were introduced by in order to extend some of Thompson's results about odd groups to groups with dihedral Sylow 2-subgroups.
Constrained Delaunay triangulation         
Constrained Delaunay Triangulation
In computational geometry, a constrained Delaunay triangulation is a generalization of the Delaunay triangulation that forces certain required segments into the triangulation as edges, unlike the Delaunay triangulation itself which is based purely on the position of a given set of vertices without regard to how they should be connected by edges. It can be computed efficiently and has applications in geographic information systems and in mesh generation.
Constrained equal awards         
Constrained equal gains
Constrained equal awards (CEA), also called constrained equal gains, is a division rule for solving bankruptcy problems. According to this rule, each claimant should receive an equal amount, except that no claimant should receive more than his/her claim.

Mendelian randomization

In epidemiology, Mendelian randomization (commonly abbreviated to MR) is a method using measured variation in genes to interrogate the causal effect of an exposure on an outcome. Under key assumptions (see below), the design reduces both reverse causation and confounding, which often substantially impede or mislead the interpretation of results from epidemiological studies.

The study design was first proposed in 1986 and subsequently described by Gray and Wheatley as a method for obtaining unbiased estimates of the effects of a putative causal variable without conducting a traditional randomized controlled trial (i.e. the "gold standard" in epidemiology for establishing causality). These authors also coined the term Mendelian randomization.
