We consider a random matrix of the form (known as a variance profile matrix), where denotes the Hadamard product of the two matrices, is a deterministic matrix, and is a random matrix. We call as a missing data matrix of when the entries of are either or . This framework is commonly used in various applied fields, such as biology, neuroscience, and network data analysis. We study the convergence and asymptotic freeness of missing data matrices of iid, elliptic, and covariance random matrices. Specifically, it is known that independent iid, elliptic, and covariance matrices converge to freely independent circular, elliptic, and Marčenko-Pastur variables, respectively. In this article, we provide the necessary and sufficient conditions on deterministic matrices for which these results hold true for independent missing data matrices of these three types of random matrices.
