Performing an analysis is not a matter of finding a software with a number fancy menus.
Most likely there is a need to shape and reshape the data before it can be used. The different sessions discuss various aspects of this work.
Here you will find some instructions and some simple description of the other sessions. (2 pages).
This session points to some macros that contain a number of exercises mainly about input and output and storage of data. There is also a particular macro for better understanding how the software handles 'time'. Many datasets contain dates and times and it is important to have a format that works well. (1 page).
Here a number of good and useful commands are listed and explained. The session is not a replacement for the on-line help but can be seen as an entery point. (6 pages).
When performing statistical analysis of data it is necessary to be able to read and handle files of different formats. Also there is very often a need to be able to manipulate columns and data sets. (5 pages).
All software for statistics can create graphs but many times these predesigned graphs are almost useless. Thus there is a need to create tailor-made graphs or at least graphs with some extra features. This can be done if the graph-creating commands are used. (15 pages).
Before the very analysis of a dataset, there is a need to shape and re-shape the data in a way that suits the
different types of analyses. This shaping of the data can take anything from a few minutes to some days. (8 pages).
