Can matrix data (e.g., correlations or covariances) instead of raw data be used for input?
Yes, STATISTICA supports a variety of matrix-file types as input data (e.g., for Regression, Factor Analysis, Reliability, and other modules). Matrix files can be edited in the spreadsheet (as if they were raw data files), however, in order to be properly interpreted as matrices by the program, they need to meet specific content and format conditions (depending on the matrix type). STATISTICA also supports the multiple matrix data file format for input in procedures (such as Structural Equation Modeling) which support matrix data for groups. Refer to the respective module of STATISTICA for details on matrix file input (press the Help button, the F1 key, or use the Electronic Manual for specific descriptions of the matrix file formats supported by STATISTICA).
