  Design Issues in Mechanical Tolerance Analysis
For assemblies with small numbers of components, or which have one component tolerance which is much greater than the remaining components, the common Statistical model can give component tolerances which are tighter than if computed by a Worst Limit model.
Statistical models assume manufacturing variations follow a Normal or classic bell-shaped distribution, symmetrically positioned at the midpoint of the tolerance limits.
The resultant assembly dimensions are used to calculate the statistical moments of the assembly distribution and then estimate the fraction of rejects.

  Statistical unit - Wikipedia, the free encyclopedia
In different statistical disciplines, the statistical unit is the source of a random variable.
We may be interested in a unit because we intend to generalize from observations on a few units to a statistical assembly of units.
We may be interested in the internal functioning of a unit which we can characterize as a statistical assembly.

Observations of a variety of statistical attributes is a common way of studying relationships among the attributes of a single unit.
We may really be interested in a statistical population (or set) of similar units rather than in any statistical unit per se.
Our interest may be focused on a statistical assembly where we examine functional subunits of the statistical unit.

Such assemblies would be a cross between modern juries (made up of a representative sample of ordinary citizens), and modern debating chambers (that at present are restricted to elected politicians).
In a Statistical Direct Assembly views would be taken after people had followed debate and heard witnesses and so all the complex and involved pros and cons (something which might take several days) – in other words, after considered opinion formation – far from the instant judgments of opinion polls.
But a Statistical Direct Assembly, using a sample deliberately selected to reflect society, would produce a view (because it is a statistical mirror) as if all people had listened carefully, and knew that their vote made a difference.

 Statistical assembly - Wikipédia
A statistical assembly is a study of the relationships among the components in a statistical unit that is made of discrete components like organs or machine parts.
Much of the observation for statistical assembly requires special preparation of the unit, which demands that the intervention must not prejudice the observations.
A simple version of this kind of research uses the stimulus-response model.

If ongoing telecommunication were possible between government statistical agencies and their data suppliers, the chunks of data requested from survey respondents might smaller in size, while more frequent in number, timed to be close to the events being measured (e.g., consumer purchases).
One common issue underlying all the trends is the potential use of technology, either in the hands of sample respondents or in the hands of statistical agencies, to improve participation in government surveys and to enhance the accuracy of their data.
It was created in late 1992 to address a severe technical professional education need of the Federal statistical system, caused by the fact that traditional disciplines were not giving their graduates the knowledge necessary for the design, collection, and analysis of economic and demographic statistical information systems.

 Robust Self-Assembly Using Highly Designable Structures   (Site not responding. Last check: 2007-10-21)
As a final observation on the application of self-assembly, complex artifacts often consist of a series of levels, where the components used at one level of the structure are in turn formed from a smaller set of components [38].
Instead, the statistical nature of self-assembly gives rise to a variety of statistical regularities when the number of components is large.
One way to reduce the number of local minima is through another statistical property of systems with many components: with a sufficient number of ways to change a structure, i.e., a sufficiently high dimensional space of configurations, there is likely to be at least one direction in the space allowing the energy to decrease.

In the DNA and electrophoresis-assisted assembly approach, a DNA-like polymer film is put on the individual units and a complementary film is patterned on the circuit (or a handle wafer) surface where the units are to be placed.
The assembly process described requires a human or robotics arm to physically pick, align, and attach a centimeter sized packaged surface mount device onto a substrate.
This process of locating device heterostructures in recesses of the wafer's surface through statistical assembly, and doing the final device patterning, processing, and integration after assembly at the wafer level and in a batch mode is illustrated generally in FIGS.
