## Software

http://www.gnu.org/software/pspp/

This is a free version of SPSS called PSPP which claims to perform descriptive statistics, T-tests, anova, linear and logistic regression, cluster analysis, factor analysis, non-parametric tests and more.https://www.jamovi.org

A free-to-use spreadsheet front end attaching itself to the R statistical language to enable gui use of some of its functions.http://www.presidion.com/academic-portal

Free student registration to look at youtube videos of how to use and interpret all the statistical methods available in SPSS. To access the full site you need to send proof to Presidion who manage SPSS academic licences of 'lecturer' status to presidion e.g. link to a web page with that information, some documentation from the college, email from head of department etc. irene.garcia@presidion.com or sara.carr@presidion.com are contacts (as of February 2015).http://calculators.stat.ucla.edu/

Genetic Power Calculator (Sean Purcell and P C Sham)http://www.bristol.ac.uk/cmm/research/ebooks/

Stat-JR v1.0.5 is the first release of Stat-JR to include a suite of statistical analysis assistants (SAAs). The scope of the SAAs ranges from modelling a simple linear regression through to a combined SAA that will cope with: different response types (normal, binomial, Poisson and negative-binomial); multiple levels/classifications at which random effects can occur in both a nested or crossed way; random intercepts and slopes and interaction terms. Many of the SAAs use MLwiN (both IGLS and MCMC estimation) as the engine underneath the electronic book thereby joining up Stat-JR and MLwiN software packages that we distribute together. This software is free to academics.https://www.cmm.bris.ac.uk/lemma
