hi all,

Summary provides Std.Errors for the free cells of matrices specified in the top model.

Questions:

Is there any way to get SEs for Algebras?

Given that SEs are not obtainable currently for Algebraic matrices - how should Std.Errors - in particular the 95%CIs of a matrix - be calculated when standardizing a solution?

Do the CIs of values in a the standardized matrix retain properties as the unstandardized? For instance, that a given CI doesn't include 0?

In that case, can one obtain the SE of a standardised parameter simply by re-scaling the SE to have the same relative magnitude as held for the unstandardised parameter and SE?
