Significance of correlations in dataset

Alex Rasker
Dear List,

I run the following syntax (generalized) to compute a set of correlations:

CORRELATIONS
/VARIABLES = V1 V2 V3 V11 V12
/MISSING = PAIRWISE
/MATRIX OUT(*).

and I get two blocks of data in my dataset. The first block contains the
number of valid cases for each correlation and the second block contains the
actual correlations. In the output window, if I don't suppress it, I have
the significance level for each correlation as well, arguably one of the
more relevant pieces of information. If I understand the 'Help' facility
correctly I should also have the significance levels available in the
dataset as well. Unfortunately, I can not seem to get them there. I am very
keen on achieving this though since I would like to continue my calculations
based on more information than just the correlations itself.

Does anyone know how to accomplish this, either by simple syntax or via OMS
- commands or otherwise?

Thanks.
Regards, Alex

Re: [BULK] Significance of correlations in dataset

Beadle, ViAnn
Matrix datasets do not include the significance level because this would be completely redundant information usually not required by the application which is going to read the correlations.

If you do just want to display the significance levels to look at, they are in the viewer file?

For what application are you creating this matrix dataset?
