Usage

1
inits(bug, warn.mess = TRUE)

Arguments

bug

A time series BUGS model created using the tsbugs package.

warn.mess

Print warning message notifying users that the initial values simple guesses and have nothing to do with data. Default is TRUE.

Details

The inits function is intended to provide a set of candidate initial values for BUGS models created using the tsbugs package. The list provided from inits does not guarantee that BUGS model will run from an efficient set of starting points, or indeed that the BUGS model will run at all. Values are set to be in the parameter space and are not based on the data used to create the tsbugs model. If problems do occur running the BUGS model, users are advised to set their own initial values.

Value

list with components dependent on model type.
