MicrOsiris Statistical Analysis and Data Management Software and Decision Tree for Statistics (Freeware)
MicrOsiris is a comprehensive statistical and data management package for Windows. Derived from OSIRIS IV, a statistical and data management package developed and used at the University of Michigan, MicrOsiris includes special techniques for data mining (SEARCH) and analysis of nominal- and ordinal-scaled data (MNA, MCA) and an interface to Michigan Survey Research Center‘s missing values imputation variance estimation and regression software for complex sampling designs, IVEware (included with MicrOsiris).

MicrOsiris is powerful and fast. MicrOsiris loads in less than 1.2MB of memory with additional memory allocated as needed to handle any sized dataset and analysis. This allows MicrOsiris to easily handle up to 80,000 variables and can import up to 20,000 variables (from SPSS, SAS, STATA, and Excel) and to process thousands of records without any appreciable slow down (e.g., 100,000 records with SEARCH). These features make it ideal for applied survey research methods as well as large-scale research projects. MicrOsiris can also read datasets from the enormous store of survey data available in the original OSIRIS format from the Inter-University Consortium for Political and Social Research (ICPSR) at the University of Michigan.
MicrOsiris is easy to learn. The Decision Tree for Statistics included with MicrOsiris helps select statistics or statistical techniques appropriate for the purpose and conditions of a particular analysis and to select the MicrOsiris commands which produce them.

MicrOsiris is free. MicrOsiris may be used free of charge and can be re-distributed to others (with attribution). This, along with its speed and small footprint make it an excellent choice for college- or graduate-level courses in research and statistics.
