Replacing ACE to ADE in bivariate moderation model

[doge73]

Dear Community,

Thank you very much for your effort on the UMX. I would like to propose another feature in the bivariate moderation model, replacing ACE with ADE, in the umxGxEbiv function.

Given my knowledge, I think the major change will be:
Replace: umxMatrix("PsC", "Symm", nrow = 4, ncol = 4, free = FALSE, values = c(1, 0, 1.0, 0, 1, 0, 1.0, 1, 0, 1)),
To : umxMatrix("PsDmz", "Symm", nrow = 4, ncol = 4, free = FALSE, values = c(1, 0, 1.0, 0, 1, 0, 1.0, 1, 0, 1)),
umxMatrix("PsDdz", "Symm", nrow = 4, ncol = 4, free = FALSE, values = c(1, 0, 0.25, 0, 1, 0, 0.25, 1, 0, 1)),

Best
