OUTFILE Subcommand (QUANTILE REGRESSION command)

The OUTFILE subcommand controls the statistics to be saved in external data files or previously declared datasets.

COVB = 'savfile' | dataset
The optional keyword writes the covariance matrix of the parameter estimates to an external data file or a previously declared dataset. When only one value is specified for /CRITERIA QUANTILE, 'savfile' and dataset are used to name the external data file or dataset. When multiple values are specified, each quantile is saved to an external data file or dataset. An underscore "_" followed by a meaningful quantile suffix is automatically appended to the data file name or dataset name. For example, /CRITERIA QUANTILE = 0.25 0.50 0.75 saves three data files with 25, 50, and 75 appended to their data file names before the extension suffix .sav.
More digits can be added to the quantile suffix (for example, when /CRITERIA QUANTILE = 0.502 0.503 is specified).
Note that the decimal point and the leading 0 before the decimal point are not used in the suffix. A scientific notation, if specified for /CRITERIA QUANTILE, is converted to a decimal value when displayed in the suffix.
CORB = 'savfile' | dataset
The optional keyword writes the correlation matrix of the parameter estimates to an external data file or previously declared dataset. The rule to name the external data file or dataset names is the same as described in COVB = 'savfile' | dataset.
FILE_SEPARATE = {FALSE**} {TRUE}
The optional keyword controls whether or not the correlation and/or covariance matrices of the parameter estimates (when multiple quantiles are specified) are saved in a single external data file or dataset. The keyword takes effect only when multiple values are specified for /CRITERIA QUANTILE. FALSE is the default setting, which saves the matrices in a single external data file or dataset. When TRUE is specified, the matrices are saved in multiple external data files or datasets. The rule to name the external data files is the same as described in COVB or CORB. The following rules apply when a dataset is used for COVB and/or CORB:
  • When /CRITERIA QUANTILE contains a single value, or when FILESEPARATE = FALSE, a single DATASET DECLARE dataset is inserted before the QUANTILE REGRESSION command.
  • When /CRITERIA QUANTILE contains multiple values (for example, 0.40 and 0.60), and when FILESEPARATE = FALSE, DATASET DECLARE dataset_40 and DATASET DECLARE dataset_60 are inserted before the QUANTILE REGRESSION command.
{MODEL = 'filename'} {PARAMETER = 'filename'}
The required keyword specifies the target file name and controls whether the variance-covariance matrix of the parameter estimates (together with the other model information and statistics), is written to a PMML file. When MODEL = 'filename' is specified, the variance-covariance matrix is written to the target file. When PARAMETER = 'filename' is specified,the target file does not contain the variance-covariance matrix. In either case, a valid file name must be specified.
When only one value is specified for /CRITERIA QUANTILE, 'filename' is used to name the target file.
When multiple values are specified, each quantile saves a separate PMML file. An underscore "_" followed by a meaningful quantile suffix is automatically appended to the file name. For example, /CRITERIA QUANTILE = 0.25 0.50 0.75 saves three data files with 25, 50, and 75 appended to their data file names before the extension suffix .pmml.
More digits can be added to the quantile suffix (for example, when /CRITERIA QUANTILE = 0.502 0.503 is specified).
Note that the decimal point and the leading 0 before the decimal point are not used in the suffix. A scientific notation, if specified for /CRITERIA QUANTILE, is converted to a decimal value when displayed in the suffix.
