[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
