This may have been addressed before in the context of other parameters from various platforms, so apologies if so. My question pertains to fit indexes between LISREL/Mplus/Rstats(Lavaan package). Specifically, while the CFI between Mplus/Lavaan is the same, the CFI in LISREL is on the order +.10. This is also in the context of other fit statistics which are generally close between all three (e.g., SRMR). Any idea as to the 'more favorable' CFI generated by LISREL?
