You could try umetrics (SIMCA), I think the trial version is free. 

Thank you Okta

This is a guess but what about R

Yes Peter Thank you, By using R we can do multivariate,We are still learning to use the program (it seemed not so easy ). Therefore we ask, maybe there are other (easier) free software(s) (maybe like Unscramble from Camo)

Hello! you can use PAST, this is a free software and quite friendly. You can download it on this website:

http://nhm2.uio.no/norlex/past/download.html

More information:

http://palaeo-electronica.org/2001_1/past/issue1_01.htm

Thank you Enrique

you can use AMOS

like Peter, you can do it with R, package VEGAN, good luck!

Use the =MVNORM(), =MVCOPULA(), or =MVEMPIRICAL() functions in Simetar at www.stimetar.com

Also the =CSND() generates correlated normal deviates and =CUSD() genrates correlated uniform deviates.

Thank you  James, Pablo, and M

You can try PSPP, which is quite similar to SPSS but has less options. PCA is possible but not PLS etc. https://www.gnu.org/software/pspp/. It is free. Success!

Dear all,

The SPSs can be obtain via internet.

Helena

Thank you Marcel and Helena

Thank you Mohamed and SM

I am also voting in favor of R. There are many approaches to the fundamental problem of robustness in multivariable analysis available in R. There is an R-program for comparison of 50 versions of such procedures in application to 10 well-known data sets  (called MDtests) in the book identified below. 

http://www.math-gnostics.com/Guide to Gnostic Analysis

Thank you Pavel, unfortunately I cannot open the address URL that you described above

Try again to open www.math-gnostics.com. The "Guide to Gnostic Analysis" is the title of the book available for download. It is a collection of helps to R-functions also available there. 

Pavel

Thank you again, now I can download your book

Open source R is the best, but evaluation is slow, but you can easily prepared graph in both PCA ,PLs, etc.

As to slow evaluation in using R mentioned by Jayanta:

1) There are faster implementations than R-project, but not freely available. The speed differences measureable in seconds or even in miliseconds do not play a role for students while free availability does.

2) There is a lot of functions available in R not implemented in commercial packages.

3) Students should have approach to recent state of art which is not yet reflected by popular commercial software packages (for instance the robust and information maximizing methods of mathematical gnostics).

Yes Pavel kovanic

Absolutely right freely available R project is based, actually I excited Unscrambler ,,Matlab both are commercial, but there also available weka also free, rapid miner ,.If any one follow course eraer project  there student also download Matlab for one month .

In addition to the above remarks, I would advise to use the integrated R-studio installation of R. Combined with the EDx courses available, eg: https://courses.edx.org/courses/UTAustinX/UT.7.01x/3T2014/56c5437b88fa43cf828bff5371c6a924/,

your students could have a very fast course in R applications. Especially for PCA, not so may alternatives are availble for free. The several R-applications I have used, are quite easy to use and give very nice graphical results, although finally tweaking the graphs to one's preferences may be quite hard. But it is all free to download and use. And the speed of the final calculation is not important when compared to the time one has to spend to tune the R scripts;)

Dear all,

You can try via internet to obtain SPSS

Hi Gunawan. 

you can try this online tool http://www.metaboanalyst.ca. It is very handy and produces nice charts with high resolutions. 

Best regards, 

Islam

Dear Gunawan Indrayanto

have a look here

https://github.com/gmrandazzo/QStudioMetrics/releases

you can find QStudioMetrics, an opensource software for multivariate analysis.

The software It is able to run PCA/PLS using the NIPALS algorithm. Moreover it is able to run Linear Discriminant Analysis and Multiple Linear Regression.

The software runs under graphical user interface and it process CSV as well as TXT input files. You do not need to write code. It works on Linux, OSX and Windows 64 bit. I think you can use it for metabolomic analyisis and for any kind of multivariate model development (signal analysis, QSAR/QSPR, Big data analytics and so on).

Best regards

Thank you very much

FYI, Some of my students use Orange software (biolab) for spectra data analysis. it is just free and easy.

There is the Orange software, from University of Ljubljana, object-programming type, you don't even have to know programming, only data treatment.

https://orange.biolab.si/

there is a classification toolbox for MATLAB, released by Milano Chemometrics and QSAR research Group.

http://www.michem.unimib.it/download/matlab-toolboxes/classification-toolbox-for-matlab/

The best program I know of and that is freely available is Past. This is software used for geological research but PCA is at least one of the tools that is incorporated in the software. If you use it then they would you to mention that in the paper. The website is: https://folk.uio.no/ohammer/past/ Success, Marcel

For PCA you could try ClustVis (https://biit.cs.ut.ee/clustvis/) or BioVinci (https://vinci.bioturing.com/panel/workset/build/principal-component-analysis). Both run online so don't require any downloads.

The best commercial software I have used for multivariate analysis is the Unscrambler X (https://www.camo.com/unscrambler/); you can get a free 30 day trial.

Take a look at

The best.

I work with Metabolomics and use Metaboanalyst.It gives you a R script you can use later

Thank you Elisa and Amir, with best wishes, Gunawan

I can recommend R CRAN. https://cran.r-project.org/

There are couple GUIs for it: RStudio, RkWard...

Try google

THe examples:

https://cran.r-project.org/web/packages/ChemometricsWithR/ChemometricsWithR.pdf

Thanks a lot

SIMCA?

PAST is friedly user

R is the best with a lot of libraries of multivariate analysis such as vegan, ade4, etc...

You can try Origin, Manitab and OPSTAT softwares

STATA 13.0 is a best to perform PCA

Hello, you can type factor in command area of your data set saved in stata format. From this you will get a table summarizing your results based on PCA.

For graphics (Bi-plots), I advise you to use origin software

Dear Dr. Gunawan Indrayanto,

Hi, NTSYS-pc and PAST are user-friendly software; Also, you can able to visually edit the graph. You can try R (vegan package ) if you can use this program.

Best regards,

Saeed

Hi, Statistical software R and SPSS are totally. You can use anyoneof them but i suggest SPSS for you as you are not a statistician.

Hello,

I am trying to perform a classification model using SIMCA algorithm. My data have 5 different classes: class 1 - 5 samples; class 2 - 6 samples; class 3 - 7 samples; class 4 - 6 samples and Class 5 - 16 samples. Each sample is a spectra data. How can I perform the SIMCA model? I am using the unsumcrable software.

Thanks,

PS

Hi, thanks a lot for your message. Sorry, I think I cannot help you, my old version of Unscramble was saved in my old laptop, presently I do not have any new Unscramble (it is expensive); usually I asked my students to use free software or demo software, if it is needed. Many new analytical instruments are already completed with MVA software, so it will be very helpful. I think you can read "help" to know how to do the calculation (SIMCA), or you can send email to CAMO for asking, I think they will help you (I have asked many things to CAMO many years ago, as I used this unscramble, and they always responded). With best wishes, Gunawan

Dear Gunawan Indrayanto and Pedro N Sampaio

Everything is possible with python, using scikit-learn (https://scikit-learn.org/stable/). I used to do my statistics with the Unscrambler as well, but since I found python and scikit-learn, I dont use anymore Unscrambler.

Of courses, you will need to learn to program but there are lot of examples related to multivariate analysis, check it out.

All the best

You can download Minitab free trial version for 30 days.

R statistical software comes with a lot of packages that can get the job done.

Past and NTSYS-pc

http://www.metaboanalyst.ca

this one is the best free soft. for PCA to me

Thanks a lot for all your answers, sorry I am late to responds. With best wishes

MATLAB and R is good one in this regard.

PAST is a freeware data analyzer software app filed under calculators and made available by Oyvind Hammer for Windows.

https://past.en.lo4d.com/windows

Thanks to you all

For PCA , PAST

Sorry Brother No and I am sorry for late reply

You can also use Past version 3

You can use an add-in called XLSTAT in excel, Prof. However the program is not free, the price is around 4-5 millions for academicians per year. Here is the website: https://www.xlstat.com/en/

The libraries vegan, ade4, FactoMineR are really good for multivariate analysis. The last have a very simple graphical interface.

Thanks for al your answers, with best regards, GI

R is the best free software for PCA

Open Software "R" can be helpful for your purpose.

Please use XSTAT statistical tool

You can follow SPSS, R or STATA

Thanks a lot for your information

R is the best...

Orange data mining freeware (biolab) can be used also but only 2D plot can show in PCA

Use R please

Dear Prof. Indrayanto,

as previously suggested, the R software looks the software you are looking for. It is free and there are multiple packages which offers the analysis you need. For PCA and HCA I suggest you the package "FactoMineR", while "MixOmics" can be a good alternative for PCA but also for the different types of PLS or CCA analysis methods.

Thanks a lot for your nice information, With best wishes, Gunawan

Matlab and Chemometric toolbox from David Ballabio website.

Past software
