A Random Matrix Approach to Dynamic Factors in macroeconomic data
arXiv:1201.6544 · doi:10.12693/APhysPolA.121.B-110
Abstract
We show how random matrix theory can be applied to develop new algorithms to extract dynamic factors from macroeconomic time series. In particular, we consider a limit where the number of random variables N and the number of consecutive time measurements T are large but the ratio N / T is fixed. In this regime the underlying random matrices are asymptotically equivalent to Free Random Variables (FRV).Application of these methods for macroeconomic indicators for Poland economy is also presented.
