SIMULATE: Create a SIMULATE specification for use in rblimp()

In rblimp: Integration of 'Blimp' Software into R

Create a SIMULATE specification for use in rblimp()

Description

Creates a simulation specification that can be passed to rblimp() as the data argument. Instead of reading existing data, rblimp() will use Blimp's SIMULATE command to generate data and then fit the specified model to it.

Usage

SIMULATE(model, n, define = NULL, variables = NULL)

Arguments

model	Character string or vector specifying data generation equations. Same format as rblimp_sim().
n	Sample size. For single-level: integer. For multilevel: named list.
define	Character vector or string of parameter definitions (optional).
variables	Formula or character string specifying which variables to save (optional).

Value

A blimp_simulate object (subclass of blimp_syntax) that can be passed to rblimp() as the data argument.

Examples

# Create simulation specification
sim_spec <- SIMULATE(
  model = c(
    "x = normal(0, 1)",
    "y = normal(10 + x*0.5, 1)"
  ),
  n = 1000
)

# View the specification
print(sim_spec)

# Use in rblimp to fit a model to simulated data
mdl <- rblimp(
  model = "y ~ x",
  data = sim_spec,
  seed = 123,
  burn = 5000,
  iter = 5000
)
