IBM® SPSS® Amos™ 28
Assigns values to the matrix of sample covariances, where sample covariances are stored as a one-dimensional array. This method should not be used if means/intercepts are explicit model parameters, because it sets the vector of sample means to zero. (Use PutSampleMomentsPacked instead.) If your sample covariances are stored in a two-dimensional array, use PutSampleCovariances.
Syntax
object.PutSampleCovariancesPacked (covarianceMatrix)
object.PutSampleCovariancesPacked (covarianceMatrix, groupNumber)
The PutSampleCovariancesPacked method syntax has the following parts:
Part |
Description |
object |
An object of type AmosEngine. |
covarianceMatrix |
A one-dimensional array of type double. The lower triangular elements of covarianceMatrix should be stored in the order x(0,0), x(1,0), x(1,1),..... |
groupNumber |
Optional. A group number. The first group is group number 1. If groupNumber is omitted, the first group is used. |
Placement: [3].
Remarks
One efficient technique for performing a sampling study is to loop through the following sequence.
1.Generate a new sample covariance matrix.
2.Use PutSampleCovariancesPacked.
3.Use FitModel.
