A command that appears in the Multivariate statistics menu if you select a TableOfReal. It calculates the multivariate means for the different row labels from the selected TableOfReal.
The following commands
Create TableOfReal (Pols 1973): "no"
To TableOfReal (means by row labels): 0
will result in a new TableOfReal that has 12 rows. Each row will contain the mean F1, F2 and F3 values for a particular vowel. These means were obtained from 50 representations of that vowel.
If we had chosen the expansion:
To TableOfReal (means by row labels): "yes"
the resulting TableOfReal would have had 600 rows. This representation comes in handy when, for example, you have to calculate deviations from the mean.
