TWO WAYS TO GET UNSTUCK
Start with a diagnosis.
Go further if you need to.
Most students only need the diagnosis. If the model has to be rebuilt, the full rescue covers it.
Full rescue
$900
Your diagnosis fee counts toward it
- I re-specify and re-run the model
- A short memo explaining the changes for your committee
I take a limited number of diagnoses each week so the 72-hour turnaround holds. If this week is full, I'll tell you when yours starts before you pay.
WHAT TO SEND
Your output,
not your data.
Most problems can be diagnosed from what the software prints. That keeps participant data out of it and avoids IRB data-sharing issues.
The exact warning
Copy the warning or error message word for word, including the first line.
Your model syntax
The lavaan model string, your Mplus input file, or for AMOS, a description of the model.
Your full output
All of it, not just the warning. In lavaan:
summary(fit, fit.measures = TRUE, standardized = TRUE).Sample size, covariances, and means
The covariance matrix and means of the variables in your model, for example
round(cov(dat), 4)andround(colMeans(dat), 4)in R. If you have missing data, say how you handled it.

This is consulting, not ghostwriting. Every fix comes with an explanation you can defend, and I encourage you to tell your advisor you got statistical help.
