Parametric models are often regarded as less flexible than non-parametric models but if the outcome variable follows an identifiable distribution, these kinds of procedures can be very powerful. This means it is assumed that the dependent variable follows a specific distribution. Unlike the existing Life Tables, Kaplan-Meier and Cox Regression procedures, the newly added Accelerated Failure Time Model is parametric in nature. Version 29 brings a new addition to the SPSS family of Survival analysis procedures. Version 29 introduces some new analysis procedures and includes more recent versions of R and Python Parametric Accelerated Failure Time (AFT) Models

Local IT teams will be able to advise on this.In September this year, IBM released the latest version of SPSS Statistics. Any administrative staff who have a need to use SPSS will need to purchase an individual licence.

The full licencing terms can be reviewed online.Īdministrative use is not allowed with the research and teaching licence. The licence allows use for teaching and research purposes both at work and at home. It is worth noting that SPSS is now only licenced for academic staff and students. Managed staff desktop users should contact their local IT teams for advice on doing this.Īdditionally, all access to SPSS 16 on managed machines will be automatically removed in September this year (SPSS 16 is no longer available to download from the ESD and SPSS 19 will cease to be available from September 2012). If you are currently using an earlier version of SPSS, note that you will need to update to version 20 before end of December 2012 (due to licencing restrictions and/or withdrawal of specific versions by IBM). Further information about licensing, together with licence codes, can be found on the Applications Software Website. This is to facilitate time for teaching staff to assess any lecture notes and test functionality, in time for the next academic year. IT Services are pleased announce that SPSS 20 is now available on the Electronic Software Delivery system (ESD) in anticipation of it being the standard version on the Student Desktop from September. Users of earlier versions should update before the end of December. Release of SPSS 20 (statistical software)
