  • UVa Licensed SPSS on Ivy Windows VM

     SPSS Overview SPSS (or Statistical Package for Social Sciences), was initially developed as a social survey project but later on has grown to encompass statistical
    applications in almost all disciplines. Different industries use SPSS for their data analysis work. Its features include database management, reporting,
    graphing, among many others.
    SPSS Usage SPSS is available only on the Windows VM at the moment. To run SPSS go to:
    Start Menu > All Programs > IBM SPSS Statistics Licensing We have a limited number of SPSS licenses available, which are provided on a first-come-first-serve basis.
    As a consequence, availability of SPSS on your VM is not always guaranteed once a VM request is submitted.

  • UVa Licensed IDL on Ivy Linux VMs

     IDL Overview IDL, short for Interactive Data Language, is an interactive shell based data analysis programming language. Used vastly in medical imaging, it can quickly create visualizations and graphs
    of large data sets in a few easy steps due to its vector nature. FORTRAN users would be familiar with the IDL syntax. IDL is not to be confused with
    Java IDL or Microsoft IDL.
    Basic IDL Usage To start IDL, open a terminal window and type idl. This will start the interactive shell.
    Variables in IDL To initialize variables in IDL, type:
    <variable_name> = <variable_value> e.g.
    x = 3 and hit Enter/Return

  • UVa Licensed MATLAB on Ivy Linux Virtual Machines

     MATLAB Overview MATLAB is a high-performance language for technical computing. It integrates
    computation, visualization, and programming environment. MATLAB stands for MATrix LABoratory. MATLAB was made
    to provide easy access to matrix software developed by the LINPACK (linear system package)
    and EISPACK (Eigen system package) projects. MATLAB includes a programming language
    environment with built-in editing and debugging tools, and supports object-oriented programming.
    Programming in MATLAB MATLAB has many advantages compared to conventional computer languages (e.g.,
    C, FORTRAN) for solving technical problems. MATLAB is an interactive system whose
    basic data element is an array, and almost all problems can be solved in MATLAB using that
