How do I block for "month" in a 2^(4-1) fractional factorial design?

I have 4 factors & plan on doing 8 runs. I'm wondering if I can block 4 of the runs for the 1 month I run those experiments, and 4 of the runs the next month that I run the experiment - basically 2 blocks of size 4. Would adding month as a blocking factor mean I now have 5 factors in my design? How would that look in a model & what would that alias structure look like? Somewhat related - I'd like...

How to optimize factors with uncertainty in 1 step with JMP?

Hello community!!,A question: will it be possible for the profiler to find the best combinations of factors with uncertainty when performing a simulation, which maximize the total utility and minimize the total cost, generating a table of the best combinations found? For example:

Design of Experiments with hard-to-change factor and blocking

Dear JMP community, I am using the DoE JMP Custom Design Platform to build the following design:* 4 continuous factors (2 hard to change and 2 easy to change)* 1 blocking factor* 18 experiments should be conducted in two days (9 in the first day and 9 in the second)A possible effect between both days should be modelled with the blocking factor by constructing two blocks with 9 runs per block. Now,...

Adding candidate runs in mixture design

HI, Is it possible to include candidate runs in mixture design. When i tried to add 4 runs that i wanted to include in the design. It is considering them as another factors. So, may someone explain how this works?

I have lingering confusion about blocking variables in my design and analysis.

Hi all, I'm using JMP Pro 15.2.1.I have lingering confusion about blocking in a designed experiment. In particular, whether I am indeed blocking at all.In my experiment, I have three 2-level (on/off) factors of interest. The response variable is the time-to-perform a task. I want to do a 2x2x2 factorial and I'm interested in testing the significance of main effects and 2-way interactions. I have 2...

removing terms from a model following a designed experment

Ok, suppose I've conducted a full factorial design with four 2-level factors. When fitting the model I've included all 2-way interactions. Some of the factors' main effects and interactions are not significant at 0.05. If I then remove the least significant factors (those at the bottom of the effect summary table), some of the non-significant terms become significant. If I were trying to develop t...

how to get fixed effect tests table to appear

I have a continuous response variable (Average) and a categorical predictor (Treatment) with labels 1 through 14 indicating the 14 levels. I have set the Treatment variable as ordinal, and was able to use the fit model function to obtain the least squares means table and least square means plot. However, I am unable to figure out how to obtain a table for a type 3 test of fixed effects. Specifical...

Caution: Places where Jmp does something unexpected

Definitely, JMP is Not a Spreadsheet . And that's great!! Besides this difference, there are other places where Jmp doesn't do/behave/produce what a newbie / innocent Jmp user expects.
If a user knows these issues and the remedies and workarounds - he/she can
a) save a lot of time b) be safe from data loss c) be sure that the results are as expected.

Getting NonEstimable values when crossing variables due to control setup

Hi, I'm working on a dataset where we are testing the effects of 2 treatments and the delay between them, and I'm trying to figure out how to line up my variables so I can do a Dunnett's test against various controls. We are giving animals a dose of drug A (Variable A), waiting some time (T), and then giving them a dose of drug B . If the animal is NOT given drug A (= 0), then T doesn't have a m...

How to adjust the factor range for specific factors within an ongoing DOE

Hi, I designed a DOE that has two independent buffers. This DOE will range components in each buffer which will be used in a processing step sequentially. IE, buffer A, followed by buffer B. We already prepared for the DOE, and formulated the A buffers as per the recommended design. For the B buffers, we intended on ranging 2 components but later decided to reduce to ranging one component, and als...

Discrete Choice Experiment: Prohibited Combination

Hi everyone,I would like to design my first DCE. I am going to use 6 attributes that differ in the levels from 2 to 4 levels. However, I have a limitation where there is an impossible combination that may appear; for example, the cheapest product would not be possible to have the best feature. Is there any way for me to select the prohibited combination? Or, is the D-optimal design will always cal...
