Hi!
Minitab numbers the runs in Yates' order (standard order in Minitab).
Is there a way to sort the runs in Yates' order in JMP?
I want to create Yates' order for 18 factor design but Minitab is limited to 15 factors.
Thank you!
One of the choices before you click Make Table is the Run Order. This option defaults to randomization. Click on the drop-down menu and select Keep The Same, Sort Left to Right, or Sort Right to Left. One of these (I believe) is Yate's order.
Why do you want to sort the runs this way?
Sorry, it worked for 3 factor full factorial but it none of the options woked for 15 factor 2-level fractional factorial.
They are different from Minitab's standard order.
You can use the Change Generating Rules section after you select a design (e.g., 32 runs, unblocked, regular fractional factorial) to obtain a different fraction. It will not necessarily have the same resolution as the original fraction that you selected and will have different aliases.
JMP produces a minimum aberration design for the simplest alias structure. There are many other fractions (e.g., 2^(15-9)) possible, of course, each with different aliases. JMP arbitrarily chooses the first n columns for which the design would be a full factorial (e.g.,2^6 = 32, so n = 6) and then introduces the remaining factors(e.g., 9) by taking higher-order columns from the model matrix that is used in the regression analysis to estimate the parameters. These columns are no longer available for estimation.
Generally speaking the generating rules and the resulting fraction with its associated aliases are not that important because we do not have prior knowledge sufficient to know which factors and factor effects are important to choose one fraction over another. That is, you could permute/exchange the factors and still expect the same performance from the design. We depend in the key screening principles for any of the factions to succeed.
Why do you need a particular fraction?
