PASW Statistics Base

PASW Statistics Base forms the basis of many deployments with statistical tests and procedures that are fundamental to many analyses.

  • Overview
  • Features

You can take the analytical process from start to finish with PASW Statistics Base. In addition to the data preparation, data management, output management and charting features now available in all PASW Statistics modules, PASW Statistics Base offers the most frequently used procedures for statistical analysis that are the foundation for many analyses.

PASW Statistics Base contains many fundamental procedures analysts need.

The procedures within PASW Statistics Base will enable you to get a quick look at your data, formulate hypotheses for additional testing, and then carry out a number of procedures to help clarify relationships between variables, create clusters, identify trends and make predictions.

In PASW Statistics Base 18, you'll find the following enhancements:

  • New nonparametric tests allow multiple comparisons and operate on large datasets more efficiently. Tests include: Chi-square, binomial, runs, one-sample, two independent samples, k-independent samples, two related samples, k-related samples and descriptives.
  • Charts for statistical process control tests now include rule-checking on secondary charts

The fundamental procedures within PASW Statistics Base allow you to get an understanding of the basic structure of your data and formulate hypotheses for additional testing, and then carry out a number of procedures to help clarify relationships between variables, create clusters, identify trends and make predictions.

A number of tests and procedures are multithreaded for improved performance, including the SORT operation, plus correlation, partial correlation, linear regression, and factor analysis procedures.
