10 Chapter 1. The CORR Procedure<br />

KENDALL<br />

requests a table of Kendall’s tau-b coefficients based on the number of concordant<br />

and discordant pairs of observations. Kendall’s tau-b ranges from −1 to 1.<br />

The KENDALL option is invalid if a WEIGHT statement is used. If you use a<br />

PARTIAL statement, probability values for Kendall’s partial tau-b are not available.<br />

NOCORR<br />

suppresses displaying of Pearson correlations. If you specify the OUTP= option, the<br />

data set type remains CORR. To change the data set type to COV, CSSCP, or SSCP,<br />

use the TYPE= data set option.<br />

NOMISS<br />

excludes observations with missing values from the analysis. Otherwise, PROC<br />

CORR computes correlation statistics using all of the nonmissing pairs of variables.<br />

Using the NOMISS option is computationally more efficient.<br />

NOPRINT<br />

suppresses all displayed output. Use NOPRINT if you want to create an output data<br />

set only.<br />

NOPROB<br />

suppresses displaying the probabilities associated with each correlation coefficient.<br />

NOSIMPLE<br />

suppresses printing simple descriptive statistics for each variable. However, if you<br />

request an output data set, the output data set still contains simple descriptive statistics<br />

for the variables.<br />

OUTH=output-data-set<br />

creates an output data set containing Hoeffding’s D statistics. The contents of the<br />

output data set are similar to the OUTP= data set. When you specify the OUTH=<br />

option, the Hoeffding’s D statistics will be displayed, and the Pearson correlations<br />

will be displayed only if the PEARSON, ALPHA, COV, CSSCP, SSCP, or OUT=<br />

option is also specified.<br />

OUTK=output-data-set<br />

creates an output data set containing Kendall correlation statistics. The contents of<br />

the output data set are similar to those of the OUTP= data set. When you specify the<br />

OUTK= option, the Kendall correlation statistics will be displayed, and the Pearson<br />

correlations will be displayed only if the PEARSON, ALPHA, COV, CSSCP, SSCP,<br />

or OUT= option is also specified.<br />

OUTP=output-data-set<br />

OUT=output-data-set<br />

creates an output data set containing Pearson correlation statistics. This data set also<br />

includes means, standard deviations, and the number of observations. The value of<br />

the –TYPE– variable is ‘CORR.’ When you specify the OUTP= option, the Pearson<br />

correlations will also be displayed. If you specify the ALPHA option, the output data<br />

set also contains six observations with Cronbach’s coefficient alpha.
