A Tool for Sensitivity Analysis in Structural Equation Modeling R package SEMsens version 1.5.5 CRAN Task View: Psychometrics (https://CRAN.R-project.org/view=Psychometrics) Perform sensitivity analysis in structural equation modeling using meta-heuristic optimization methods (e.g., ant colony optimization and others). The references for the proposed methods are: (1) Leite, W., & Shen, Z., Marcoulides, K., Fish, C., & Harring, J. (2022). <doi:10.1080/10705511.2021.1881786> (2) Harring, J. R., McNeish, D.
