[R] Is SEM package of R suitable for sem analysis
Dears, I'm a college student and In doing my statistics homework. I use R with SEM package as my tool for sem analysis, but my teacher told me AMOS is more suitable for such analysis. Could someone help tell me whether it is true that some commercial software is better accepted in academic fields? Sorry if I should not post such topics here. -- Best Regards, Reeyarn T.

A few years ago it could have been true, but now the package has improved (especially with the bootstrap procedure). At the moment there is no argument to recommend AMOS. Of course, some software like Mplus are actually better, but very specialized (and rather expensive). This is only a personal point of view.

I am going to take SEM this next quarter in my doctoral program. My suggestion is to use the program your professor suggests and try to re-create your models in R using the SEM package. We are not going to use AMOS though we use EQS, and another prof on campus who teaches it in a different department uses LISREL, so since SEM hasn't been implemented in most commercial software and you need specialty software for it, it may be best to know several different software programs if you want to do SEM type work. I do have a feeling since R is growing so rapidly it wont take time for people in the community to create packages or develop existing packages equal to or greater than commercial software!

Your welcome, I wanted to say I agree with Bruno that the comparative software is very expensive, even more prohibitively so for students and even though MPlus is good I think R will catch up rapidly and even overtake those as people who use these modeling techniques become more integrated into the R community.

Well, I guess it will be extremely difficult to persuade your teacher to use the sem package in R. AFAIK, AMOS and LISREL have become the golden standard for SEM in China, and SEM has become a golden model for analysis in social science and psychology. I have been a cynic to SEM for a long time, because I strongly believe this model has been completely abused, and perhaps the "easy-to-use" AMOS has been helping people abuse SEM. A common phenomenon I see is, people do not care about the model at all - all they care about is whether AMOS can successfully compute the coefficients; if AMOS failed, they will try to (randomly) set constraints to the model, i.e. add/remove this arrow, drag some variables into/out of the model, set this coefficient/variance to 1. Anyway, I encourage you to ask your teacher why AMOS is "more suitable". I have a couple of very ridiculous stories about the SEM software, in which I can only feel the blind faith in software. Sigh... The good thing is, R is open source, so is the sem package. You can see everything in it, and you can extend it as you wish (in case your teacher think it is less suitable).
