cor
Compute Pearson product-moment (ordinary) correlations for the specified series or groups.
Syntax
cor(options) arg1 [arg2 arg3...]
where arg1, arg2, etc. are the names of series or groups.
Note that this command is a limited feature version of the group view Group::cor.
Options
 
wgt=name (optional)
Name of series containing weights.
wgtmethod=arg (default = “sstdev”)
Weighting method (when weights are specified using “weight=”): frequency (“freq”), inverse of variances (“var”), inverse of standard deviation (“stdev”), scaled inverse of variances (“svar”), scaled inverse of standard deviations (“sstdev”).
pairwise
Compute using pairwise deletion of observations with missing cases (pairwise samples).
out=name
Basename for saving output. All results will be saved in Sym matrices named using the string “CORR”, appended to the basename (e.g., the correlation specified by “out=my” is saved in the Sym matrix “MYCORR”).
prompt
Force the dialog to appear from within a program.
p
Print the result.
Examples
cor height weight age
displays a Pearson correlation matrix for the three series HEIGHT, WEIGHT, and AGE.
