Correlate
includes Bivariate and Partial Correlations. The procedure also computes
distance statistics that measure similarities or
dissimilarities
Bivariate:
This analysis is used to obtain correlation coefficients, a measure of linear
relationship between two variables. It computes Pearson’s correlation
coefficient, Spearman’s rho and Kendall’s tau-b. You can request for one-tailed
or two-tailed significance probabilities.
Options: Gives us the means and standard deviations of the variables. For
missing values, you can choose to exclude cases pairwise or listwise. |
Partial:
This analysis is used to obtain correlation coefficients after controlling for
one or more variables. Partial correlation describes the relationship between
two variables while controlling for the effects of one or more variables
Options: Gives us the means and standard deviations of the variables. You
can request for zero-order correlations which are the simple correlations
between any pair of variables, including the controlled variables. For
missing values, you can choose to exclude cases pairwise or listwise |
Distances: Calculates similarities and dissimilarities between pairs of cases or pairs of variables. These distance measures can be used in other procedures like factor analysis or cluster analysis.
The data set used for this demonstration is the Body Fat data set. See Data Set page for details. The body fat data has 4 variables; the amount of body fat, triceps skin fold thickness, thigh circumference, and mid-arm circumference.
