Traditional methods of factor analysis, such as Structural Equation Modeling (SEM) and factor regression, lack properties desirable for analyzing big data, such as the ability to handle high\u2010dimensionality or the ability to enforce sparsity on the estimates of the factor loading matrices. These methods also assume that the number of latent constructs is known beforehand, a problem unique to factor analysis that often goes unaddressed or overlooked, with ad hoc methods being the most common ways to deal with such a fundamental question. Although recent developments in the literature have attempted to remedy these issues, particularly with regard to expanding SEM to high\u2010dimensional and sparse applications, there is a noticeable lack of such methods that do so using likelihood theory. To rectify this shortcoming, we propose a new SEM\u2010based method for estimation that utilizes maximum likelihood theory while simultaneously addressing some of the most common problems associated with big data. We substantiate our method through simulation studies, indicating that the proposed method can correctly identify the latent factors underlying the independent and dependent sets of variables, while also accurately estimating the entries of and enforcing sparsity upon the factor loading matrix estimates. We apply this method to the COVIDiSTRESS Global Survey dataset, a global survey collected to further our understanding of how the COVID\u201019 pandemic affected the human experience. Doing so demonstrates the performance of the model while simultaneously identifying the latent constructs intrinsic to the data.<\/jats:p>","DOI":"10.1002\/sim.70171","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T00:59:07Z","timestamp":1752800347000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Maximum Likelihood Method for High\u2010Dimensional Structural Equation Modeling"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5602-2036","authenticated-orcid":false,"given":"Alexander","family":"Quinter","sequence":"first","affiliation":[{"name":"Department of Biostatistics University of North Carolina Gillings School of Public Health  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5478-2269","authenticated-orcid":false,"given":"Xianming","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of North Carolina Gillings School of Public Health  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donglin","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of North Carolina Gillings School of Public Health  Chapel Hill North Carolina USA"},{"name":"Department of Biostatistics University of Michigan School of Public Health  Ann Arbor Michigan USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2428-6552","authenticated-orcid":false,"given":"Joseph G.","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Biostatistics University of North Carolina Gillings School of Public Health  Chapel Hill North Carolina USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,17]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41597\u2010020\u201000784\u20109"},{"key":"e_1_2_8_3_1","volume-title":"Mplus User's Guide","author":"Muth\u00e8n L.","year":"2017"},{"key":"e_1_2_8_4_1","unstructured":"SAS Institute Inc.Cary \u201cNorth Carolina User's Guide. 14.1 \u201d2015."},{"key":"e_1_2_8_5_1","volume-title":"IBM SPSS for Windows","author":"IBM Corp.Armonk","year":"2020"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v048.i02"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2517-6161.1996.tb02080.x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1198\/016214506000000735"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1080\/10705511.2016.1154793"},{"key":"e_1_2_8_10_1","volume-title":"lessSEM: Non\u2010Smooth Regularization for Structural Equation Models","author":"Orzek J.
