A theorem of Kalman and minimal state-space realization of Vector Autoregressive Models

Du Nguyen

We introduce a concept of (AR)state-space realization that could be applied to all transfer functions with invertible. We s…

Vector Autoregressive Moving Average Model with Scalar Moving Average

Du Nguyen

We show Vector Autoregressive Moving Average models with scalar Moving Average components could be estimated by generalized least square (GLS) for each fixed moving average polynom…

Rayleigh Quotient Iteration, cubic convergence, and second covariant derivative

Du Nguyen

We generalize the Rayleigh Quotient Iteration (RQI) to the problem of solving a nonlinear equation where the variables are divided into two subsets, one satisfying additional equal…
