ctsem (version 3.0.1)

ctStanModel: Convert a frequentist (omx) ctsem model specification to Bayesian (Stan).

Description

Convert a frequentist (omx) ctsem model specification to Bayesian (Stan).

Usage

ctStanModel(ctmodelobj, type = "stanct")

Arguments

ctmodelobj

ctsem model object of type 'omx' (default)

type

either 'stanct' for continuous time, or 'standt' for discrete time.

Value

List object of class ctStanModel, with random effects specified for any intercept type parameters (T0MEANS, MANIFESTMEANS, and or CINT), and time independent predictor effects for all parameters. Adjust these after initial specification by directly editing the pars subobject, so model$pars .

Examples

# NOT RUN {
model <- ctModel(type='omx', Tpoints=50,
n.latent=2, n.manifest=1, 
manifestNames='sunspots', 
latentNames=c('ss_level', 'ss_velocity'),
LAMBDA=matrix(c( 1, 'ma1' ), nrow=1, ncol=2),
DRIFT=matrix(c(0, 1,   'a21', 'a22'), nrow=2, ncol=2, byrow=TRUE),
MANIFESTMEANS=matrix(c('m1'), nrow=1, ncol=1),
# MANIFESTVAR=matrix(0, nrow=1, ncol=1),
CINT=matrix(c(0, 0), nrow=2, ncol=1),
DIFFUSION=matrix(c(
  0, 0,
  0, "diffusion"), ncol=2, nrow=2, byrow=TRUE))
