Forecasting in the presence of in-sample and out-of-sample breaks

J Xu, P Perron - Empirical Economics, 2023 - Springer
We present a frequentist-based approach to forecast time series in the presence of in-
sample and out-of-sample breaks in the parameters of the forecasting model. We first model …

[图书][B] How liquid is the CDS market?

A Fulop, L Lescourret - 2014 - researchgate.net
A common belief is to qualify the credit default swap (CDS) market as very liquid. However,
looking at intra-daily CDS data on individual firms from a major interdealer broker, we find …

Input design for nonlinear stochastic dynamic systems–A particle filter approach

RB Gopaluni, TB Schön, AG Wills - IFAC Proceedings Volumes, 2011 - Elsevier
We propose an algorithm for optimal input design in nonlinear stochastic dynamic systems.
The approach relies on minimizing a function of the covariance of the parameter estimates of …
