A command that creates a Covariance object from each selected SSCP object.

Setting

Number of constraints

determines the factor by which each entry in the SSCP-matrix is scaled to obtain the Covariance matrix.

Details

The relation between the numbers c_ij in the covariance matrix and the numbers s_ij in the originating SSCP matrix is:

Normally numberOfConstraints will equal 1. However, when the SSCP was the result of summing g SSCP objects, as is, for example, the case when you obtained the total within-groups SSCP from pooling the individual group SSCP's, numberOfConstraints will equal the number of pooled SSCP's, g.
