[R] Fractional Factorial Design on 4-level factor

2016-05-31 Thread Michael Haenlein
Dear all, I am running a simulation experiment with 8 factors that each have 4 levels. Each combination is repeated 100 times. If I run a full factorial this would mean 100*8^4 = 409,600 runs. I am trying to reduce the number of scenarios to run using a fractional factorial design. I'm interested

[R] Fractional Factorial Design

2008-04-28 Thread Caio Azevedo
Hi all, Does anybody know if it is possible to build a fractional factorial design in R? That is, suppose that we want do design an experiment with 3 factors with 2, 3 and 3 levels, respectivly. However we want to consider, let's say, only 6 from all possible level combinations. Does R design such
