  • 1.  SPSS is written on...

    In Wikipedia article "Comparison of Statistical Packages" https://en.m.wikipedia.org/wiki/Comparison_of_statistical_packages in the first table, we observe that SPSS Statistics is written in "Java".

    Well, as far as I'm aware, only (or mostly) the frontend is written Java. The majority of backend, libraries doing analyses or graphs, are wtitten in C or Fortran. Am I correct or not? Java isn't enough fast for computational programming.

    Should the Wikipedia entry be accordingly corrected therefore?

    Kirill;

    You are right. The backend is a mixture of C++ and FORTRAN.

    To be technically accurate, the SPSS Statistics backend does have some Java code that runs for certain purposes (and Python and R for programmability and extensions). But it is correct that the vast majority of the algorithmic pieces, apart from some embedded SPSS Analytic Server code which is Java, is written in Fortran and C/C++.

    Best,
