Hi, I am exactly replicating the SEM model which was done in SAS using Proc Calis in R. Used sem package in R but not getting the GFI as same as in SAS (approximately 15% difference) and also one link is insignificant but in SAS am getting significant. Searched through online in different blogs but not able to get the solution. Please let me know what might be the reason. Thanks,Vinay ? ? ? ? [[alternative HTML version deleted]]
