Arguments
object 
Object to generate random draws. An object of class

nsim 
The number of draws (one draw simulates a data set of the size that is defined by ntimes); defaults to 1. 
seed 
Set the seed. 
times 
(optional) An indicator vector indicating for which times in the complete series to generate the data. For internal use. 
is.prior 
For 
... 
Not used currently. 
Details
For a depmix
model, simulate generates nsim
random state
sequences, each of the same length as the observation sequence in the
depmix
model (i.e., sum(ntimes(object))
. The state
sequences are then used to generate nsim
observation sequences
of thee same length.
For a mix
model, simulate generates nsim
random class
assignments for each case. Those assigments are then used to generate
observation/response values from the appropriate distributions.
Setting the times
option selects the time points in the total
state/observation sequence (i.e., counting is continued over ntimes).
Direct calls of simulate with the times
option are not recommended.
Value
For a depmix
object, a new object of class depmix.sim
.
For a transInit
object, a state sequence.
For a response
object, an observation sequence.
