In light of the growth in vertically specialized in global trade, the present paper uses input– output tables from the World Input–Output Database to construct an environmental multi-regional input–output model to calculate the CO₂ emissions embodied in China's international trade during...

Titterington proposed a recursive parameter estimation algorithm for finite mixture models. However, due to the well known problem of singularities and multiple maximum, minimum and saddle points that are possible on the likelihood surfaces, convergence analysis has seldom been made in the past...
