• Factor Constraints disappears center points and some other strange behavior

  Hello.I tried to create a custom design with 5 continous, 2 discrete numeric and 1 categorial factor (all 2 levels). I wanted 4 center points and 3 replicates. This works fine, until I try to define a factor constraint. I have a continues factor "storage period" with the level 0 hours and 48 hours and 2 storage places (categorial), 1 in the production environment, 1 in a controlled climate room. A...

• Blocking Factor with Varying Distributions

  I am a heavy user of DOE with up to 8-factors and one blocking variable.  Each block is subjected to a condition over time.  The problem is the S/N ratio improves over that time.  Assume the distribution is normal and just the width decreases over time.  Another key is the time at which each block is removed from the test is unknown prior to the test and is uncontrolled.  And each block can be rem...

• Fit Y by X Nominal Variables

  Hi All, I'm having trouble using Fit Y by X. It works when I used a this one particular Y variable, which is 2 levels (e.g., 'yes', 'no'), character type, nominal. The X variables I've used are also character type, nominal, but range from 2-5 levels (e.g., 'increase', 'decrease', 'no change'). But when I use a different Y variable, also 2 levels (e.g., 'low', 'high'), character type, nominal, it d...
