An efficient EM algorithm for both element-wise and structural missingness in matrix-variate normal mixture models
Hanzhang Lu, Jeffrey L. Andrews, Ryan P. Browne
Matrix-variate data with missing entries arise frequently in applications where observations are naturally organized as two-dimensional arrays. Although the matrix normal distribut…
