Output Data Sets
OUT= Data Set
The OUT= data set contains all the variables in the original data
set plus new variables containing the canonical variable scores.
The number of new variables is twice
that specified by the NCAN= option.
The names of the new variables are formed by concatenating
the values given by the VPREFIX= and WPREFIX= options (the
defaults are V and W) with the numbers 1, 2, 3, and so on.
The new variables have mean 0 and variance equal to 1.
An OUT= data set cannot be created if the DATA=
data set is TYPE=CORR, COV, FACTOR, SSCP, UCORR,
or UCOV or if a PARTIAL statement is used.
OUTSTAT= Data Set
The OUTSTAT= data set is similar to the TYPE=CORR or TYPE=UCORR
data set produced by the CORR procedure, but it contains
several results in addition to those produced by PROC CORR.
The new data set contains the following variables:
- the BY variables, if any
- two new character variables, _TYPE_ and _NAME_
- Intercept, if the INT option is used
- the variables analyzed (those in the VAR
statement and the WITH statement)
Each observation in the new data set contains some
type of statistic as indicated by the _TYPE_ variable.
The values of the _TYPE_ variable are as follows:
- _TYPE_
- Contents
- USTD
- uncorrected standard deviations.
When you specify the NOINT option in the PROC CANCORR
statement, the OUTSTAT= data set contains standard
deviations not corrected for the mean (_TYPE_='USTD').
- N
- number of observations on which the analysis is based.
This value is the same for each variable.
- SUMWGT
- sum of the weights if a WEIGHT statement is used.
This value is the same for each variable.
- CORR
- correlations.
The _NAME_ variable contains the name of the variable
corresponding to each row of the correlation matrix.
- UCORR
- uncorrected correlation matrix.
When you specify the NOINT option in the PROC CANCORR
statement, the OUTSTAT= data set contains a matrix
of correlations not corrected for the means.
- CANCORR
- canonical correlations
- SCORE
- standardized canonical coefficients.
The _NAME_ variable contains the name of the canonical variable.
- RAWSCORE
- raw canonical coefficients
- USCORE
- scoring coefficients to be applied without
subtracting the mean from the raw variables.
These are standardized canonical
coefficients computed under a NOINT model.
- STRUCTUR
- canonical structure
- RSQUARED
- R2s for the multiple regression analyses
- ADJRSQ
- adjusted R2s
- LCLRSQ
- approximate 95% lower confidence limits for the R2s
- UCLRSQ
- approximate 95% upper confidence limits for the R2s
- F
- F statistics for the multiple regression analyses
- PROBF
- probability levels for the F statistics
- CORRB
- correlations among the regression coefficient estimates
- STB
- standardized regression coefficients.
The _NAME_ variable contains
the name of the dependent variable.
- B
- raw regression coefficients
- SEB
- standard errors of the regression coefficients
- LCLB
- 95% lower confidence limits for the
regression coefficients
- MEAN
- means
- STD
- standard deviations
- UCLB
- 95% upper confidence limits for the
regression coefficients
- T
- t statistics for the regression coefficients
- PROBT
- probability levels for the t statistics
- SPCORR
- semipartial correlations between
regressors and dependent variables
- SQSPCORR
- squared semipartial correlations between
regressors and dependent variables
- PCORR
- partial correlations between regressors and dependent variables
- SQPCORR
- squared partial correlations between
regressors and dependent variables
