Definition - What does PSPP mean?
PSPP is an open-source application used for statistical analysis of sampled data. Considered as an alternative to the proprietary statistics application, IBM SPSS, it is similar in many aspects to the SPSS application. PSPP is considered a powerful tool for data pre-processing, data visualization, data analysis and hypothesis testing, and is aimed at social scientists, students and statisticians. The name has no official expansion.
Techopedia explains PSPP
PSPP was created as an open-source replacement for the data management and analysis tool SPSS. The proprietary licensing of SPSS and the digital restrictions management led to the birth of the functionally identical PSPP. Similar to other open-source applications, PSPP can be copied, shared or modified and can be obtained in the same manner as other GNU software applications. PSPP is developed using the C programming language and makes use of the GNU Scientific Library for mathematical routines. PSPP can access some of the libraries programmatically.
PSPP can work on most operating systems and computer hardware. It is a stable and reliable application and can support over a billion cases and variables. One of the unique features of PSPP is its interoperability with other software applications such as Openoffice.org and Libre Office. PSPP has a fully indexed user manual and supports all common character sets and can translate to multiple languages. PSPP has data view tabs, variable view tabs, output windows and a layout identical to that of SPSS. Another feature of the application is that it can work in either graphical user interface or traditional command line mode.
The application is capable of performing tasks such as:
- Linear regression
- Data re-ordering
- On-parametric testing
- Cluster analysis
- Logistic regression
- Reliability testing
- Principal components analysis
- Factor analysis
- Chi-square analysis
The application is also capable of producing statistical graphs such as pie-charts, histograms and np-charts. The output is available in formats such as PDF, HTML, ASCII, SVG and Post Script. There is no expiration period, license agreements or license fees associated with PSPP.
