On CARMA estimation in YUIMA

Q: Can YUIMA manage with statistical inference the following model? # yuima.model object model <- setModel(drift = c("-3*x1","x1*x2"), diffusion = matrix(c("1","0"),2,1), state.variable = c("x1","x2"),…


R Code for calculating standard errors(p-values) in COGARCH

To determine p-values and or standard errors for estimates, we combine the estimation method for COGARCH in yuima with the bootstrap methodology. Here you can find an example of the code tha we used in our work "Discrete‐Time Approximation of a…


Lévy CARMA models for shocks in mortality

Abstract. Recent literature on mortality modeling suggests to include in the dynamics of mortality rates the effects of time, age, the interaction of these two and a term for possible shocks. In this paper we investigate models that use Legendre…

How to set real data in a yuima object

Q: I've had trouble setting up CARMA objects with real data. After defining a carma model carma.model, I call setYuima(data=setData(mydata), model=carma.model), and get the error message "Error in if (dim([email protected])[2] == 1){ : is of length…
