Inflationary Pressure Tracking in Euro Area: A Matrix Dynamic Factor Approach with Missing Data Resolution

This paper applies dynamic factor models for matrix-valued time series on euro area inflation panel and develops inflationary pressure indices for eura area countries and extend the model to estimate missing data employing the matrix structure.
