How should I treat a factor with range or value that is dependent on the level of another factor in a DOE?
Hello, I am designing a DOE with 4 factors. My problem is that the range for 2 factors are dependent on the level of 1 of the factors. For example: Factor 1 - low (1), medium (2), high (3) If Factor 1 is at low setting, then Factor 2 settings are low (1), medium (2), high (3). If Factor 1 is at high setting, then Factor 2 settings are low (3), medium (4), high (6). The range or values for lo...
