Multivariate Analysis: Correlation Analysis

Tables Tab

The Tables tab is shown in Figure 25.8. You can use the Tables tab to display the following tables that summarize the results of the analysis:

Pearson’s product-moment


displays a table of Pearson correlation coefficients. Selecting this check box corresponds to the PEARSON option in the PROC CORR statement. Clearing this check box corresponds to the NOCORR option in the PROC CORR statement.

Hoeffding’s D


displays a table of Hoeffding’s statistic. This statistic is not available if you specify variables in the Partial Variables list on the Variables tab. This check box corresponds to the HOEFFDING option in the PROC CORR statement.

Kendall’s tau-b


displays a table of Kendall’s tau-b statistic. This check box corresponds to the KENDALL option in the PROC CORR statement.

Spearman’s rho


displays a table of Spearman’s rank-order correlation. This check box corresponds to the SPEARMAN option in the PROC CORR statement.

Show significance probabilities for H0: correlation=0


displays -values under the null hypothesis of zero correlation. Clearing this check box corresponds to the NOPROB option in the PROC CORR statement.

Simple descriptive statistics


displays descriptive statistics for the variables in the analysis. Clearing this check box corresponds to the NOSIMPLE option in the PROC CORR statement.

Covariances


displays the covariance matrix for the variables in the analysis. This check box corresponds to the COV option in the PROC CORR statement.

Cronbach’s coefficient alpha for estimating reliability


displays Cronbach’s coefficient alpha for the variables in the analysis. This check box corresponds to the ALPHA option in the PROC CORR statement. This statistic is not available if you specify variables in the X Variables (With) list on the Variables tab. This statistic is not available unless you select Listwise for Exclude missing values.

Exclude missing values


specifies how to treat missing values in the analysis. If you select Listwise, then observations with missing values are excluded from the analysis. Listwise corresponds to the NOMISS option in the PROC CORR statement. Otherwise, statistics are computed using all of the nonmissing pairs of variables.
