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 …

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 …

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 …
