OpenMx 2.0 Discussion

Zero-inflated poisson counts using mxThreshold

mxCI results in 2.18.1 and 2.19.1 are different
This is the code from the example of mxCI:
# From the example of mxCI()
# generate data
covariance <- matrix(c(1.0, 0.5, 0.5, 1.0),
nrow=2,
dimnames=list(c("a", "b"), c("a", "b")))
data <- mxData(covariance, "cov", numObs=100)

help: "Cov" is not positive definite.
Thank you for your awesome software. I have been working on a TSSEM and once I run my attached codes on the data in the excel file attached, I get the message below after the first stage regression is completed:

In the ACE Model:warning messages during my data analysis
When I use ACE model to calculate heritability,I got a warning messages during the analysis(See Attachment). Is there a problem with my data and will it affect the results?
when there was a warning message, I found that the estimated results will change under different start values.
Could you please provide me more details?
Thank you very much.
Best regards,

checkpoints in tryHard
I'm running large-ish models with mxTryHard, but notice checkpoints aren't an option as with mxRun. Is there still a way to save / load progress as I go?
Thanks!
