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.
