TYPE=EST Data Sets
A TYPE=EST data set contains parameter estimates. The
CALIS, CATMOD, LIFEREG, LOGISTIC, NLIN, ORTHOREG, PHREG, PROBIT,
and REG procedures create TYPE=EST data sets when the
OUTEST= option is specified. A TYPE=EST data set produced
by PROC LIFEREG, PROC ORTHOREG, or PROC REG can be used with PROC SCORE to
compute residuals or predicted values.
The variables in a TYPE=EST data set include
- the BY variables, if a BY statement is used
- _TYPE_, a character variable of length eight,
that indicates the type of estimate. The values depend on
which procedure created the data set. Usually a value of
'PARM' or 'PARMS' indicates estimated regression coefficients, and
a value of 'COV' or 'COVB' indicates estimated covariances of the
parameter estimates. Some procedures, such as PROC NLIN, have
other values of _TYPE_ for special purposes.
- _NAME_, a character variable that contains the values
of the names of the rows of the covariance matrix when the procedure
outputs the covariance matrix of the parameter estimates.
- variables that contain the parameter estimates,
usually the same variables that appear in the VAR statement
or in any MODEL statement. See Chapter 19, "The CALIS Procedure,"
Chapter 22, "The CATMOD Procedure," and Chapter 45, "The NLIN Procedure," for details on the variable
names used in output data sets created by those procedures.
Other variables can be included depending on the
particular procedure and options used.
