Continuous-time state space analysis of d18O, d13C, and CO2 in the Cenozoic Era
Mikkel Bennedsen, Eric Hillebrand, Kathrine Larsen +2
We develop a continuous-time state-space framework for the joint reconstruction of three Cenozoic climate proxies, benthic foraminiferal d18O and d13C and atmospheric CO2, from irr…

Continuous-time state-space methods for d18O and d13C in the Cenozoic Era
Mikkel Bennedsen, Eric Hillebrand, Siem Jan Koopman +2
Time series analysis of d18O and d13C from benthic foraminifera for paleoclimatology poses significant challenges. The data span tens of millions of years, with sparse early record…

Estimating breakpoints between climate states in the Cenozoic Era
Mikkel Bennedsen, Eric Hillebrand, Siem Jan Koopman +1
This study presents a statistical time-domain approach for identifying transitions between climate states, referred to as breakpoints, using well-established econometric tools. We…
