The ORTHOREG Procedure

Output Data Set

The OUTEST= option produces a TYPE=EST output SAS data set that contains the BY variables, parameter estimates, and four special variables. For each new value of the BY variables, PROC ORTHOREG outputs an observation to the OUTEST= data set. The variables in the data set are as follows:

  • parameter estimates for all variables listed in the MODEL statement

  • BY variables

  • _TYPE_, which is a character variable with the value PARMS for every observation

  • _NAME_, which is a character variable left blank for every observation

  • _RMSE_, which is the root mean square error (the estimate of the standard deviation of the true errors)

  • Intercept, which is the estimated intercept. This variable does not exist in the OUTEST= data set if the NOINT option is specified.
