SOSstat Features


In this page you will find a list of the main features of SOSstat

What’s new in SOSstat 3


SOSstat2 users won’t be disoriented by the GUI of version 3 since they will find the usual cutting with the area of ​​data, the area of results, as well as projects in the reporting areas.

Note, however, important new features :

  • SOSstat3 can open multiple data grids at the same time

  • Data grids are similar to spreadsheets with mouse selection and cells formatting.

  • Les nombre de lignes et de colonnes n’est pas limité (il dépend toutefois de la mémoire disponible sur l’ordinateur)
  • A new feature called “report” appeared. It is a streamlined word processor integrated SOSstat, which allows the user to build a custom report throughout analyzes .

  • The result area is being also transformed since it is possible to display multiple graphs that are resizable and repositionable

  • Graphics can be operated in vector formats are the advantage is to provide scientific quality prints. It also have the advantage of being modified with a vector drawing software (Powerpoint, LibreOffice-Draw, Inkscape, Visio ...)

  • The assistants of analysis are more comprehensive
