GxE model for binary variable
I want to use the code posted in [there](http://ibg.colorado.edu/cdrom2016/franic/Moderation/Practical/DO_NOT_OPEN_Moderating_covariances_practical_solved.R), but this code is suit for continuous variable and I don't know how to change it to be suit for binary variable. Could you tell me what lines I should change or add?
Because I'm pressed for time, I am sorry to directly ask for solution instead of learning by myself.

Multivariate ACE-ADE model
I am trying to fit a 5-variate model. But I am not sure about the best way to do it.
I have got these results from the univariate analyses
VAR1
ADE 0.34 0.10 0.57
AE 0.42 * 0.58
VAR2
ADE 0.26 0.16 0.58
AE 0.41 * 0.59
VAR3
ACE 0.29 0.13 0.58
AE 0.45 * 0.55
CE * 0.33 0.67
VAR4
ADE 0.23 0.17 0.59
AE 0.39 * 0.61

Why mxTryHardOrdinal（）dosen't report start values?
When i use
SatFit <- mxTryHardOrdinal(SatModel, intervals=TRUE,extraTries = 15,finetuneGradient=FALSE,bestInitsOutput=TRUE) ,the result is Solution found! Final fit=22505.957 (started at 22819.562) (16 attempt(s): 16 valid, 0 errors). I don't know why it dosen't report start values from the best fit.

saturated univariate SEM model of a binary variable
I have some problems of fitting saturated univariate SEM model of a binary variable "whtr_g". I would appreciate it if anyone could help me.
1. I always get warning message when fitting saturated SEM model(see warning message.png), whether using SLSQP, NPSOL or CSOLNP optimizer. What’ more, the result of three optimizers are different. But I don’t know if there are errors in my code. Please help me to check it.

How to calculate bivariate h2(or c2, e2) in bivaraite SEM model with two binary traits?
I have encountered several problems in doing bivariate SEM models, which is an important part of my graduation project.The main problems are as follows:

G*E interaction with a moderator
Also, is it appropriate to see the unstandardized variance components by SES moderation, rather than the standardized variance components?

Question about Confidence Interval for Standardized path coefficients (multivariate model)
Hi everyone, I am new here and learning OpenMX. I have a problem of getting confidence interval for standardized path coefficients. Could anyone please provide me the OpenMx language about this? I also provide my scripts below and hope someone can let me know what the problem is (the script about 'ciACE <- mxCI("VC[1:5, 16:30]")' ) or how to read the output about standardized CI.
