We develop the Double Principal Component Analysis (DPCA) based on a dual factor structure for high-frequency intraday returns contaminated by microstructure noise. The dual factor structure allows a ...
We give some answers to the following question: If the binding number of a graph G is more than 1+(a-1)/b, does G have an [a,b]-factor?
