Correlations

Select menu: Stats | Summary Statistics | Correlations

Use this to form correlation, and/or partial correlations, between a number of variates. You can also calculate tests of the correlations against zero.

After you have imported your data, from the menu select
Stats | Summary Statistics | Correlations.
Fill in the fields as required then click Run.

After running, you can save the results by clicking Save.

Available data

This lists data structures appropriate to the current input field. The contents will change as you move from one field to the next. You can double-click a name to copy it to the current input field or type it in.

Data

Used to enter the names of the variates to be analysed. You can transfer multiple selections from Available data by holding the Ctrl key on your keyboard while selecting items, then click to move them all across in one action.

Weights

A variate to provide weights for the units of the data variates to replicate observations. The calculation assumes that weights are positive integers defining the replications of the values inside the data variates. A zero or negative value in the weights will exclude the associated values from the calculation of the correlation. If this field is left blank then all units have equal weighting of one.

Display

Specifies which items of output are to be displayed in the Output window:

Correlations	Symmetric matrix of correlations
Partial Correlations	Symmetric matrix of partial correlations

Test correlations against 0

Lets you choose either a one-sided or two-sided test of the correlations against 0.

Graphics

Specifies the graphs to be displayed.

Correlation plot	Plots the matrix of correlations
Partial correlation plot	Plots the matrix of partial correlations

Action buttons

Run	Run the correlation analysis.
Cancel	Close the dialog without further changes.
Defaults	Reset options to the default settings. Clicking the right mouse on this button produces a shortcut menu where you can choose to set the options using the currently stored defaults or the Genstat default settings.
Save	Opens a dialog to specify names of structures to save the results.
