I need free software (open source or that can be found in cracked version) and relatively simple one (that doesn't require coding) for doing PCA for medium sample size data (19).
Sample size: 19
Variables: 5, co-related variables.
I was using The Unscrambler software, but it is not free! Now, I am trying with spss. Is there any better software than this? What about origin?
Try R. The "stats" software package that automatically installs with R has the princomp function for PCA. Plenty of help on the internet eg http://www.instantr.com/2012/12/18/performing-a-principal-component-analysis-in-r/
Dear Sagar,
You could also use PAST (http://folk.uio.no/ohammer/past/) - it's free and very easy to handle.
Best, Thomas
Origin pro from 2016 versions have PCA. Its easy to operate. Try it
I think you need to search more links. I am not using software currently.
You might try the free excel-add in 'Real Statistics Using Excel'. You can download it from http://www.real-statistics.com/
The website also provides good tutorials.
Thank you all for your answers. For the analysis, I used spss. I found it quite good for data analysis, but the output figure was not good (visually). So, I used Minitab 17 for figures, produced quite good figures.
Working with Minitab is easy and simple. In the links below, there are other software that can be useful to you.

Many.
Here is a Matlab code with good explanation
Article Principal component analysis - a tutorial
I made a small free web utility (PCA explorer) to perform online PCA available here :

The data can be uploaded as a tab delimited file along with it's associated metadata (refer to the sample files in the webpage) and visually explore the output. You can also perform statistical analysis between the groups.
why not try Simca Umetrics or XLStat? they are good software for PCA with good output
Hi! I used rapidminer for PCA with a dataset contained 150 samples. there is no need to code in this software. Like LABview it has diagrams and graphical modules and was helpful for me.
