Digits after decimal point?

Hello, this is a more general question  does Mplus allow to change the default to show just three digits after the decimal point? 


No. If you want more decimals, you need to save the results. 


Dear Dr. Muthen, I would like to obtain more digits from the residual variance. How can I get the data with the savedata command? Thank you for your answer! 


Use the RESULTS option.

Dear Dr. Muthen, I also need more decimals in the results (lots of association tests  need very high threshold for statistical significance). The problem is that I have hundreds of models I need to run (through R or STATA) and so far I have not found an addon thing in R or STATA that allows reading in the Mplus results output saved in such a way. However, with a R package, I managed to read in the regular results printed in output files, including the zvalues. So I want to calculate the pvalues from R, using the Z values I got from Mplus. In this situation, do you think I can use the normal distribution function in R? My sample size is around 1000. For example, for a zvalue 1.771 from Mplus I type this in R > 2*pnorm(abs(1.771)) [1] 0.0765607 This gives more decimal places, which is what I need for the log 10 conversion. In Mplus the p value is 0.077. There is no way for me to be absolutely sure whether the two are identical, because the zvalue itself doesn't have more accuracy after 3rd decimal places either. Do you think the p value from Mplus is using the same distribution as in R this way? Thanks a lot!!! Kate 


Use the PHI function and MODEL CONSTRAINT. The PHI function is described in the DEFINE command.
