Hi Sir Sylvain! Sorry if I had to ask you a more specific question related to the question I earlier asked. This is what my problem is: I'm meta-analyzing effect sizes from more than 100 studies. Some studies have one effect size, or 2 effect sizes, or 3 effect sizes, and etc. Because studies have different number of effect sizes, the covariance matrices of effect sizes are then different for each study. To illustrate, I have small data set below (where Study 1 has 2 effect sizes, thus it has a 2X2 covariance matrix; Study has 3 effect sizes, thus it has a 3X3 covariance matrix; and Study 1 (has 2 missing effect sizes) so it has only 1X1 covariance matrix). So here is my question Sir, is there a code I can use to (automate) import the covariance matrix from say SAS to SAS-IML without having to type this covariance matrices into SAS-IML, given the fact that I have more than 100 studies? Study 1 = { .022 .009, .009 .023} Study 2 = { .016 .003 .006, .003 .016 .008 .006 .008 .016} Study = { .019} Thanks so much for the help. I'm new with SAS and SAS IML and I really need to figure out how I can import my data (covariance matrices) in order for me to run an analysis. Sincerely, Rommel
