OUTPUT Statement
- OUTPUT OUT= SAS-data-set
keyword=names
< ...keyword=names >;
You use the OUTPUT statement to specify a data set to receive
quantities that can be computed for every input observation, such as
extracted factors and predicted values. The following
keywords are available:
- PREDICTED
- predicted values for responses
- YRESIDUAL
- residuals for responses
- XRESIDUAL
- residuals for predictors
- XSCORE
- extracted factors (X-scores, latent vectors, T)
- YSCORE
- extracted responses (Y-scores, U)
- STDY
- standardized (centered and scaled) responses
- STDX
- standardized (centered and scaled) predictors
- H
- approximate leverage
- PRESS
- approximate predicted residuals
- TSQUARE
- scaled sum of squares of score values
- STDXSSE
- sum of squares of residuals for standardized predictors
- STDYSSE
- sum of squares of residuals for standardized responses
Suppose that there are Nx predictors and Ny responses and that
the model has Nf selected factors.
- The keywords XRESIDUAL and STDX define an output variable
for each predictor, so Nx names are required after
each one.
- The keywords PREDICTED, YRESIDUAL, STDY, and PRESS define an
output variable for each response, so Ny names are
required after each of these keywords.
- The keywords XSCORE and YSCORE specify an output variable
for each selected model factor. For these keywords, you
provide only one base name, and the variables corresponding to
each successive factor are named by appending the factor
number to the base name. For example, if Nf=3 then a
specification of XSCORE=T would produce the variables
T1, T2, and T3.
- Finally, the keywords H, TSQUARE, STDXSSE, and STDYSSE each
specify a single output variable, so only one name is
required after each of these keywords.
