Triantafyllopoulos, K. (2008) Missing observation analysis for matrix-variate time series data. Statistics and Probability Letters, 78 (16). pp. 2647-2653. ISSN 0167-7152
Bayesian inference is developed for matrix-variate dynamic linear models (MV-DLMs), in order to allow missing observation analysis, of any sub-vector or sub-matrix of the observation time series matrix. We propose modifications of the inverted Wishart and matrix t distributions, replacing the scalar degrees of freedom by a diagonal matrix of degrees of freedom. The MV-DLM is then re-defined and modifications of the updating algorithm for missing observations are suggested.
