Colleagues,
I only recently came across a free (yes, FREE!) statistical program that is described as "a program for statistical analysis of sampled data. It is a free as in freedom replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions." This is the link:
https://www.gnu.org/software/pspp/
I was very excited to find this! I ordered the PSPP Guide and the GNU PSPP Reference Manual from Amazon. If you love SPSS, you will see that this virtually mirrors SPSS in user experience, functionality, and outputs.
Has anyone used it? If s, what do you think?
