dRiftDM (version 0.3.1)

new_drift_dm: Create a DDM model --- internal

Description

This function assembles all components to create a drift_dm object.

Usage

new_drift_dm(
  flex_prms_obj,
  sigma,
  t_max,
  dt,
  dx,
  solver,
  comp_funs,
  cost_function,
  subclass,
  b_coding = NULL,
  obs_data = NULL
)

Value

A list with elements flex_prms_obj, prms_solve, solver, comp_funs, and cost_function. The object has class attributes c(subclass, "drift_dm") and an attribute "b_coding" containing the boundary coding. If obs_data is not NULL, the observed data are attached via obs_data().

Arguments

flex_prms_obj

a flex_prms object.

sigma

the diffusion noise (sigma).

t_max

the maximum trial duration (t_max).

dt

the temporal step size (dt).

dx

the evidence step size (dx).

solver

a string identifying the solver (e.g., "kfe").

comp_funs

a list of component functions.

cost_function

a string, defining how to compute the fit cost.

subclass

a string with model info label set for the child class.

b_coding

an optional list with boundary coding (e.g., drift_dm_default_b_coding()).

obs_data

an optional data.frame with observed data.

Details

We do not perform input checks here; we just assemble the object. Any pre-wrangling is done in drift_dm(). Checks are performed by validate_drift_dm(), which is called indirectly via the setters (e.g., prms_solve() and obs_data()).
