Design expert (DX7) is best softwer for DOE.

if you want i can send #free version of this softwer for you.

best rigards.

You can look on Minitab.

Dear Shahin Mohammadi

I suggest SPSS software. Of course you could use Minitab. Both are OK., but the SPSS is better, I think so.

One the best tools for DOE and is free software is R... Yes, R statistical package.... you can also do SIX SIGMA with it. Here is a tutorial:

http://www1.beuth-hochschule.de/FB_II/reports/Report-2011-004.pdf

If you ever think Six-Sigma which doesn't answer your question but is a powerful tool in industry: familiarize yourself with this :

https://jjmcd.fedorapeople.org/Download/R/R-2.13-Six_Sigma_with_R_-_A_Tutorial-en-US.pdf      (STILL INCOMPLETE)

I like this site"s advice, very much so:

Try Modde, originally developed by organic chemists.

Hi Shahin, From my experience Modde and JMP are the most complete/powerful software for DoE. You should, obviously, take into consideration your specific needs, budget, regulatory requirements (for instance in the pharma industry) as some free software (including R based packages) are available. 

My advice you can use R and besides you can use the Rcmdr.DoE.plugin which readily the analysis and the creation of the design.

I'm bound to use ... R ... but the tutorial ... does not seem to be friendly;

Design expert is more user friendly.

I use Design expert. It is powerful yet easy to use

I think Minitab is better...Is more flexible to use than Design Expert...

The problem is that there is no good program

To study 10 variables and find a polynomiale function of the third degree

Do you have an idea?

Dear Ayoub, could you please elaborate your question and clarify your statements?

@Olusegun: could you please clarify the meaning of "flexible"?

Kind regards LG

I have a problem involving 10 variables (factors)

For simulation

First you choose 100 experiences by Cordexch in Matlab

After 100 simulations I got the results

I wanted to find a polynomial function

In order to rely on them to solve the problem of optimization

polynomiale function obtained by the third degree MATLAB for 10 variables

They did not produce good results when I checked them out compared to simulation results

Is there a better way?

Dear Ayoub, there are many, many reasons why you may be failing to get the desired results. It's not IMHO feasible to give any hints without any additional info. Are you willing to share the data (100 sim's x 10 var's )? No need to identify any of them if it's "sensitive" data, as well as an example of the "not good enough" fitted poly model. It will be easier for the RG community to give you some hints. If willing to share the data, please use a commonly used format (tab delimited, csv, excel or similar). Regards, LG

Dear Luis

I do not have forms in sharing information

Regards, Ayoub

Dear Ayoub, please confirm if I got it right:

a) you have 10 independent variables (or factors or explanatory variables)

b) you have 19 dependent variables, the "Responses" (UXN1...MASS)

c) your design includes 3 levels for each factor (coded as 1, 2 and 3 in the "DOE" worksheet)

d) you have 100 experiments (factors and obtained responses)

If that is the case, why are you trying to include 3rd degree parameters in your model when you have only 3 different levels in your design? You can't fit a 3rd degree model if you have only 3 levels for the factors.

Isn't a model including only two-factor (or even 3-factor) interactions and 2nd degree parameters enough? I tested a model with the 10 factors + 45 2-factor interactions +10 2nd degree factor and was able to predict some of the Responses with a R2>0.95 (didn't try all of them).

Please confirm my interpretation of your problem/DOE.

Regards, Luis

Dear Luis

The situation is also described as you

I adopted designs for a quadratic model

I wanted to find a third degree model

I did not know it would cause a big mistake

-------------------------------------

I have 10 factors

The simulation takes a great effort

A large number of outputs

And I think a quadratic model does not work

I do not want to do more than 150 simulations

------------------------------------

What do you suggest to me?

Can I use Matlab in the same way and correct the error?

Or recommend me to another program

thank you very much

There are many software you can use. however, for simplicity i will advice you to use Design Expert version 10. its users friendly but in terms of 3D graphics i will recommend Statistica 12.5

Most of DOE software are capable of fitting second order equation, if you want to fit higher order then you need to use matlab (nlinfit command).

hi

Design expert

R is best. For comprehensive description consult the book by John Lawson: Design and Analysis of Experiments with R, CRC Press, Boca Raton, 2015.

It depends on what you prefer, but Minitab does a good job with DOE. Other packages that you can use are: R, SPSS, Design Expert, SImul8 Stat or Stata.

Design Expert

Design Expert version 11

Dear fellows, I don't usually make any comments on the other contributors' answers. However, my opinion is that "one line" answer's stating just the name & version of the software, without any consideration on its pros and cons are just garbage and do not add any useful information to any one of us. In addition, we are wasting our time reading them. Therefore, you find it reasonable, please substantiate your answers using rational and clear reasons, otherwise keep your opinions to yourself. All the best for you all sharing and spreading knowledge.

Design Expert is perfect.

I always use Design Expert 10.

The best is JMP.

Design Expert.

Design Expert & JMP Pro Statistical Discovery from SAS

Design Expert or Minitab are free?

Dear Jorge Rodríguez-Martínez ,

No, none of them is free!

However you will find R packages (which are free) developed to perform DOE.

Take a look at https://cran.r-project.org/web/views/ExperimentalDesign.html

Regards, Luis

Dear Jorge, try infostat that DOE is associated with R library. Its very cheaper.

Regards

Rodolfo, Argentina

Minitab is good

Hi,

Has anyone used statgraphics?, Do you thing Statgraphics is worst than Minitab or Design Expert? and wich of this three is more expensive?,

Thank you very much,

Hi Clemente García , what do you mean with "...is worst than...?".

It's hard, if not impossible, to answer without knowing what kind of analysis/planning(s) you want to perform?

I guess you will get more useful feedback if answering theses questions.

Regards, Luis

Hi everyone. I`m looking for a free software to desing a three-component mixture experiment. My goal is to find the best mixture for a formulation, where 3 components can vary in its proportions, according to some response variables from the mixtures/treatments. I`m new at this, so basic/simple tutorial in spanish, in addition, would be great. Thanks!

I think that minitab is very suitable especially minitab-17

I find JMP (www.jmp.com) from SAS Inc. to be the best in this space. It is a pre-eminent product and has extensive DOE libraries and documentation. I have tried DX, Minitab and other apps too, I find JMP to my liking and has best publication potential if worked on JMP. Of course it is not free.

Design expert (DX7) is best softwer for DOE.

if you want i can send #free version of this softwer for you.

best rigards.

Reza Asadi can you please share Design expert (DX7) free version with me ([email protected])

Try using R, it is free and very powerful programming language. It has a substantial amount of functionality for Design of Experiments (DoE) that is distributed over various packages. R may be intimidating at first, but being a programming language means that a code can be generated, thus allowing it to be reproduced or repeated later in the future. Also, others can comment and give feedback on your code. Many has moved from commercial softwares to R.

@Ibham Veza

Please share the DoE package name for R.
