Maximum likelihood estimation for tensor normal models via castling transforms
Harm Derksen, Visu Makam, Michael Walter
In this paper, we study sample size thresholds for maximum likelihood estimation for tensor normal models. Given the model parameters and the number of samples, we determine whethe…
