Since each column of the basic design has 50% 0s and 25% each +1s and −1s, multiplying each column, j, by σ(X j)·2 1/2 and adding μ(X j) prior to experimentation, under a general linear model hypothesis, produces a "sample" of output Y with correct first and second moments of Y.
For example, a 2 5 − 2 design is 1/4 of a two-level, five-factor factorial design. Rather than the 32 runs that would be required for the full 2 5 factorial experiment, this experiment requires only eight runs. With two generators, the number of experiments has been halved twice.
An open thesis, also known as an open dissertation, is a thesis that is freely available for members of the public to access upon publication, and often also during the planning and writing process. The decision to write an open thesis is made by the author, who will usually explain their rationale for creating an open thesis as part of the ...
The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [12] by Abraham Wald in the context of sequential tests of statistical hypotheses.

The equation of state of Soave is defined as follows: = (+). The original α-function has been replaced by the function of Mathias–Copeman: [2] = [+ + + ()].The parameters of the Mathias–Copeman equation are fitted to experimental vapor-pressure data of pure components and provide a better description of the vapor pressure than the original relation.
Experimental Design Diagram (EDD) is a diagram used in science to design an experiment.This diagram helps to identify the essential components of an experiment. It includes a title, the research hypothesis and null hypothesis, the independent variable, the levels of the independent variable, the number of trials, the dependent variable, the operational definition of the dependent variable and ...
