OSIRIS Files
Previous Topic  Next Topic 

OSIRIS is a general purpose statistical package written for use on IBM mainframes.   It is no longer actively supported.  However an enormous store of survey data are available in OSIRIS format from the Inter-University Consortium for Political and Social Research (ICPSR) at the University of Michigan.  For this reason, Stat/Transfer will read, but not write OSIRIS data.


An OSIRIS data set consists of a dictionary file and a data file.


Standard extensions:  dict, data


Reading OSIRIS data

When using OSIRIS data as input for a transfer, you should make sure that the dictionary file and the data file have the same name and the extensions .dict and .data respectively.  They should also be in the same directory.


When naming the input file in the Transfer dialog box, you must give the file with the .dict extension (the dictionary file) as the input file.  Stat/Transfer will then look in the same directory for a file of the same name, but with the .data extension and will read the input data from this file.


Stat/Transfer supports OSIRIS Type 1 data sets, which is the variant in which data are usually distributed.  The dictionary file is a binary file in which strings are represented in EBCDIC notation.  The data files were originally in that format, but the ICPSR generally distributes them in ASCII format.  Stat/Transfer will support either of these formats and automatically senses which format your data are in.


If you are downloading an OSIRIS dictionary for use with Stat/Transfer, you should use a binary file transfer mode.


OSIRIS has variable and value labels, which are supported by Stat/Transfer.


Missing Values

An OSIRIS dictionary allows for two numeric missing values.  By default, these are recognized by Stat/Transfer.  However, the default behavior can changed with the User Missing Values selection of the Options dialog box.
