Asymptotic Distributions and Confidence Regions of Open Loop Transfer Functions Obtained by Multivariate Autoregressive Modelling and Application to a Benchmark's Simulation Data

K. Mourtzanos and M. Antonopoulos-Domis.

Abstract
In this paper the asymptotic distributions of open loop transfer functions and noise sources transfer functions obtained my MAR analysis are established. The distributions are found to be normal and the covariance of the distributions is expressed in physical meaningful form. Numerical simulations are performed in order to test the theoretical findings. Also confidence regions obtained by the asymptotic distributions are constructed for the estimated transfer functions. These results are applied to the artificial data of nuclear reactor of Delft's university, known as benchmark data. It is also shown why the estimation of benchmark's transfer functions is not quite successful.
