I am trying to run an EFA with 117 items and a sample size of 333. I keep receiving the following error message:
*** FATAL ERROR THERE IS NOT ENOUGH MEMORY SPACE TO RUN Mplus ON THE CURRENT INPUT FILE. NOTE THAT THE MAXIMUM MEMORY USAGE BY Mplus 32-BIT IS LIMITED BY THE OPERATING SYSTEM. REFER TO SYSTEM REQUIREMENTS AT www.statmodel.com FOR MORE INFORMATION ABOUT THIS LIMIT. NOTE THAT THE OPERATING SYSTEM HAS NO RESTRICTION ON MEMORY USAGE FOR Mplus 64-BIT.
I'm not sure how to fix the problem and would greatly appreciate any help!
I'm new to SEM and MPlus and greatly appreciate any help. My research team developed a 117 item measure using a Likert scale and administered it to 666 participants. We were originally going to do a split sample EFA/CFA but have decided to do an ESEM with the entire sample.
The administrator in our computer lab informed that all the computers are 64-BIT. However, I am still getting the same error message above regarding Memory Space.
Could anything about my code be responsible for this error? I have included it below and greatly appreciate any guidance and your time.
TITLE: ESEM 7 Factor
DATA: FILE IS ESEM data-whole sample.dat; NOBSERVATIONS ARE 666;
VARIABLE: NAMES ARE all 117 items (<-- the message board would not let me list them all)
Thank you so much for your suggestions. They were very helpful and I was able to run the model.
Which resources can you recommend for me to read through as a beginner to ESEM that would help with interpreting the results of an ESEM? For example, if an item loaded significantly onto two or more factors, do you rely on the theory of your model to decide which factor it should load onto? We are interested in creating sub-scale scores for our measure and would need to decide which factor should retain the item.
