Often you do not have the resources for a full factorial design. In this case, a fractional factorial design is a reasonable alternative, provided that the effects of interest can be estimated. Box, ...

As designs decrease in size, fewer and fewer effects are estimable. One goal of design is to keep the effects of interest unconfounded with each other. The macros in the ADXFF file enable you to ...

A fractional factorial DOE is a means of conducting ... or (400 rpm/800 rpm). In our coating example, we would call this design a 2-level, 3-factor full factorial DOE. The number of runs would ...

For example, if your output is the thickness ... Doing a full factorial as opposed to a fractional factorial or other ...
