Design Equation Resolution For Free

Resolution III designs. These are designs in which no main effects are aliased with any other main effect, but main effects aliased with two-factor interactions and two-factor interactions may be aliased with each other. A design with is of resolution III . These are main effects only designs.

Resolution refers to the detail of the image (see image below). Images with low resolution have less detail and images with high resolution have more details. Resolution is typically measured in pixels per inch (PPI) or dot per inch (DPI).

Resolution is a measure of the degree of confounding in an experimental design. A factor or factor interaction is said to be confounded (or aliased) with another when the individual effects of the factors or factor interactions cannot be separated one from the other because of the limitations of the experimental data.

Resolution. An important property of a fractional design is its resolution or ability to separate main effects and low-order interactions from one another. Formally, if the factors are binary then the resolution of the design is the minimum word length in the defining relation excluding (1).

Resolution V DOE: A design where main effects are confounded with four factor and higher order interactions and two factor interactions are confounded with three factor interactions and higher order interactions.

For an example, for the one-half fraction design, the design is called a ?resolution of three? if a three-letter generator, ABC is used in developing the design. For the one-half fraction design, if a five-letter generator word is used, the design is called a ?resolution of five.?

Defining Relation: I = ABD = ACE = BCDE I multiplied by any letter is the same letter (e.g., I A = A). For example, to obtain the aliases for factor A, multiply all terms in the defining relation by A. The identity column I is always a column of 1's (in coded units).

The length of the shortest word in the defining relation is called the resolution of the design. Resolution describes the degree to which estimated main effects are aliased (or confounded) with estimated 2-level interactions, 3-level interactions, etc.

Design resolution. The resolution of a design is given by the length of the shortest word in the defining relation. We normally write the resolution as a subscript to the factorial design using Roman numerals.

Resolution. An important property of a fractional design is its resolution or ability to separate main effects and low-order interactions from one another. Formally, the resolution of the design is the minimum word length in the defining relation excluding (1).
