SPSS Inc. SPSS Statistics 17.0: Algorithms

SPSS Inc., 2007 — 999 p.Throughout much of the documentation, we avoid detailed discussion of the inner workings of procedures in order to promote readability. The algorithms documents are designed as a resource for those interested in the specific calculations performed by procedures.
The algorithms are available in two forms:
Integrated into the overall Help system. In the Contents tab, the Base System and each option you have installed has an Algorithms subheading in the table of contents, which in turn holds the algorithms content for procedures in that option.
In the Index tab, each procedure’s main index entry has a second-level algorithms index entry.
