dzim.control

Auxiliary for Controlling DZIM Fitting

Description

Auxiliary function for dzim fitting. Typically only used internally by dzim.fit, but may be used to construct a control argument for either function.

Usage

dzim.control(dist = c("poisson", "nb", "zip", "zinb"), trace = FALSE,
  start = NULL, order = 1, mu0 = rep(0, order), Sigma0 = diag(1,
  order), N = 1000, R = 1000, niter = 500)

Arguments

`dist`	count model family
`trace`	logical; if TRUE, display iteration history.
`start`	initial parameter values.
`order`	autoregressive order.
`mu0`	mean vector for initial state.
`Sigma0`	covariance matrix for initial state.
`N`	number of particiles in particle filtering.
`R`	number of replications in particle smoothing.
`niter`	number of iterations.

Note

The default values of N, R, and niter are chosen based on our experience. In some cases, N = 500, R = 500, and niter = 200 might be sufficient. The dzim.plot function should always be used for convergence diagnostics.
