A penalized EM algorithm incorporating missing data mechanism for Gaussian parameter estimation
Missing data rates could depend on the targeted values in many settings, including mass spectrometry-based proteomic profiling studies. Here we consider mean and covariance estimation under a multivariate Gaussian distribution with non-ignorable missingness, including scenarios in which the dimensio...
