The RMSTREG Procedure
PROC RMSTREG Statement
PROC RMSTREG <options>;
The PROC RMSTREG statement invokes the RMSTREG procedure. Table 2 summarizes the options available in the PROC RMSTREG statement.
Table 2: PROC RMSTREG Statement Options
| Option | Description |
|---|---|
| ALPHA= | Specifies the alpha level |
| DATA= | Specifies the input data set |
| ITHISTORY | Prints the iteration history of the model parameters |
| NAMELEN= | Specifies the length of effect names |
| NOPRINT | Suppresses all displayed output |
| OUTPV= | Outputs the pseudovalues used in pseudovalue regression to a SAS data set |
| SINGULAR= | Specifies the tolerance for testing the singularity |
| TAU= | Specifies the upper time limit that defines the RMST |
You can specify the following options.
- ALPHA=number
specifies the
level for 
% confidence limits. The number must be between 0 and 1; the default value is 0.05, which results in 95% intervals. This value is used as the default level for confidence limits that are computed by the MODEL statement. You can override this default by specifying the ALPHA= option in the MODEL statement. - DATA=SAS-data-set
specifies the SAS data set that contains the data to be analyzed. If you omit this option, PROC RMSTREG uses the most recently created SAS data set.
- ITHISTORY
displays the iteration history of computing estimates on the basis of the estimating equations and the final evaluation of the gradient.
- NAMELEN=n
specifies the length of effect names in tables and output data sets to be n characters long, where n is a value between 20 and 200 characters. By default, NAMELEN=20.
- NOPRINT
suppresses all displayed output. This option temporarily disables the Output Delivery System (ODS). For more information, see Chapter 23, Using the Output Delivery System.
- OUTPV=SAS-data-set
names the output data set that contains the pseudovalues that are used in the pseudovalue regression analysis. To use this option, you must also specify METHOD=PV in the MODEL statement.
-
SINGULAR=number
EPSILON=number specifies the tolerance for testing the singularity of the
matrix that is formed from the design matrix 
and for testing the singularity of the Hessian matrix upon convergence of the optimization algorithm. Appropriately, the test requires that a pivot be at least number times the original diagonal value. By default, number is 
times the machine epsilon. On most machines, the default number is approximately 
. - TAU=value
specifies the upper time limit of the RMST. The default value is the largest event time, where value must be positive.
