Robust inference in the joint modeling of multilevel zero-inflated Poisson and Cox models.
Zandkarimi E, Moghimbeigi A, Mahjub H. Zandkarimi E, et al. Stat Med. 2021 Feb 20;40(4):933-949. doi: 10.1002/sim.8811. Epub 2020 Nov 23. Stat Med. 2021. PMID: 33225454
In these models, the likelihood-based methods (such as expectation-maximization algorithm and Newton-Raphson) are used for estimating the parameters, but in the presence of contaminations, these methods are unstable. To overcome this challenge, we extend the M-estimator me …

Robust inference in the multilevel zero-inflated negative binomial model.
Zandkarimi E, Moghimbeigi A, Mahjub H, Majdzadeh R. Zandkarimi E, et al. J Appl Stat. 2019 Jul 2;47(2):287-305. doi: 10.1080/02664763.2019.1636942. eCollection 2020. J Appl Stat. 2019. PMID: 35706512 Free PMC article.
This approach achieves robustness by applying robust estimating equations in the S-step instead of estimating equations in the M-step of the EM algorithm. The robust estimation equation in the logistic component only weighs the design matrix (X) and reduces the effect of t …

Two-part zero-inflated negative binomial regression model for quantitative trait loci mapping with count trait.
Moghimbeigi A. Moghimbeigi A. J Theor Biol. 2015 May 7;372:74-80. doi: 10.1016/j.jtbi.2015.02.016. Epub 2015 Feb 26. J Theor Biol. 2015. PMID: 25728790
In this study, to overcome these challenges, I apply two-part ZINB model. The EM algorithm with Newton-Raphson method in the M-step uses for estimating parameters. An application of the two-part ZINB model for QTL mapping is considered to detect associations between the fo …
