Some of you probably have heard of this software. It was bought by SPSS many years ago. It runs under unix environment and is still largely used for tabulation market research, even if there is no longer technical support for it. There is some further info here: https://en.wikipedia.org/wiki/Quantum_(statistical_programming_language)
Do you know if it can be downloaded or purchased now? Is it part of SPSS package maybe?
Also, I would really appreciate it if anyone can link me to a forum or group in LinkedIn or anything really - where people share Quantum experience.
