Hi Guys,
We are trying to conduct a DOE for a variable factors but an attibute response. Can anyone help me on this?
What tool am I going to use? Do I need to convert the attibute response into a variable response?
Sincerely,
Mel

Mel, how many levels of the atttribute response would be, based on your anticipation? I guess the difficulty is how to analyze the data if the attribute level is 3 or even fewer. If there is a way to do the conversion, probably it is better.

Hi Will,
Yup, The level of the response is only 2 Pass / Fail.Im gonna try how can I convert this into a variable response.
Im trying to search  what kind of  DOE will I use in this attribute response.
Thanks

Mel

Hi
You would need to do repeats of each run, and calculate the % success ( or fail ). Then you will have a continious response.
You could also try to set up a full factorial ( several levels at your X’s) and analyze the data via binary regression.
Depends on how many factors you have, how much money you can spend etc etc.

Hi Maria,

Thanks for the advise. We will try and assess cost of the experiment also.

You simply need to convert the attribute data into continuous data.  This can be done using multiple subjective evaluation technique and lattice squares.  Give me your email and i’ll send you a presentation

Another approach is to try using Binary Logistic Regression (BLR) technique instead of a stright DOE.  That will help you evaluate the probaility of passing or failing.  This can only work if you have at least one variable factor (X).

george:MSE references are hard to find. It seems similar to finding principal components. I’d appreciate a copy of the pitch.Cheers, BTDT6sigmaguru(at)gmail(dot)com
