Design Resolution For Free

Resolution IV designs. These are designs in which no main effect is aliased with any other main effect or with any two-factor interaction, but two-factor interactions are aliased with other. A design with is of resolution IV . These are main effects clear designs.

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.?

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).

The resolution of a fractional factorial designs can be defined as the length of the shortest 'word' in the defining relation. It is usually denoted by italicized roman numerals. In the above designs, the shortest 'word' is a product of three variables and these designs have the Resolution III.

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.

Design resolutions describe how much the effects in a fractional factorial design are aliased with other effects. When you do a fractional factorial design, one or more of the effects are confounded, meaning they cannot be estimated separately from each other.

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.
