| Feb 1 at 7:24 | comment | added | markowitz | Probably you focused too much on the term “synonym” and misunderstood my message. I quote myself: "In Pearl's opinion, the last [SIM] is a terminological strategy for remove/obscure causal meaning at SEM (page 3)". I edited my answer for clarify better. | |
| Feb 1 at 7:22 | comment | added | markowitz | I can be agree with some things you write in last comment, for example that SEM can be seen as a broader class that SIM. More important, I read Pearl's literature carefully and, then, do not think that regressions and SEM are synonym. Indeed I write a lot in this site for defend clear separation between causal (SEM) and pure statistical (regression) concepts; read here: stats.stackexchange.com/questions/26437/… . | |
| Jan 31 at 21:42 | comment | added | wmay | Hm. Ok, after doublechecking, I see that Haavelmo's work was influential and related to SEM. But you still obviously misread Pearl. (Unless you also believe "regression analysis" is a synonym of SEM??) You might say that simultaneous EM is a subset of SEM. Obviously most SEM outside of economics is not simultaneous, so they are not synonyms. SEM is much broader than simultaneous equations, including a lot of factor analysis for example. PS: Super lame and petty to try to end the discussion that way | |
| Jan 31 at 19:05 | comment | added | markowitz | Who is confused Is clearly you. Go ahead with this discussion Is useless. I stop here. | |
| Jan 31 at 18:28 | comment | added | wmay | It's also not clear why you're going off on a digression about causality, because it's not relevant to the question. For the record, SEM is about latent variables. Simultaneous EM is about observed variables. And they are solved with completely different tools. | |
| Jan 31 at 18:25 | comment | added | wmay | You are extremely confused. Somehow you started with the (incorrect) assumption that simultaneous EM and structural EM are the same. Then you misread Pearl as a result. You wrongly claim Haavelmo was an influentual contributor to SEM. That's incorrect. SEM came from completely different people, outside of economics. Haavelmo's article is about simultaneous equation modeling, not the other SEM. | |
| Jan 30 at 7:56 | comment | added | markowitz | The problem is precisely the loss of causal understanding of SIM/SEM. The causal-free concepts/terminology that you listed are largely exploit for avoid causal meaning. SIM and SEM are far from to be a clear cut different concepts in literature. The question of the asker come from precisely from this conflation and for the same reason do not admit trivial reply. | |
| Jan 30 at 7:56 | comment | added | markowitz | Moreover even the Authors criticized by Pearl refers on the same article. Indeed many econometrics books the term SIM bring us always to speak about “structural” and reduced form … even if causal meaning are sometimes permitted and sometimes not and sometimes it is not clear. Note that for the same argument even the term SEM are sometimes used. They are extensively used as synonyms. | |
| Jan 30 at 7:56 | comment | added | markowitz | No friend, you misinterpret Pearl article. Him denunce the “steady erosion of the basic understanding of SEMs [its causal meaning]”. Simultaneous equation model (SIM) is a name that since the origin was used as synonym of structural equation model (SEM). Indeed in Pearl refers strongly to Haavelmo (1943) article, “The statistical implications of a system of simultaneous equations” as the most influential contribution for SEM! | |
| Jan 30 at 0:18 | comment | added | wmay | You misread Pearl. He did not say the two are synonyms. He gave the phrase "simultaneous equations" as an example of "causality-free nomenclature" that you might see in a SEM textbook. He also lists "covariance structure" and "regression analysis" as other examples. None of these examples are synonyms with structural equation modeling (SEM). | |

Corrected some grammar. Added some links to the author and his publications.
