“…The estimation can deal with missing data, while still being computationally efficient (Tipping & Bishop, 1999; Zheng et al, 2016). Moreover, covariates can be included in the model (Chiquet, Mariadassou, & Robin, 2017), and penalized versions of the likelihood can be used to encourage sparsity or structured sparsity, for example, in a high‐dimensional framework (Guan & Dy, 2009; Park, Wang, & Mo, 2017; Zeng, Liu, Huang, & Liang, 2017). Finally, the probabilistic formulation is very versatile, and turns several complex settings into natural extensions of the simple Gaussian ones mentioned above.…”
