Create a configuration object for the sim.NormalIG.Hierarchical function

Description

This function creates a configuration object that sets the parameters for the Hierarchical Inverse-Gamma simulation model. The configuration object is an to the sim.NormalIG.Hierarchical function.

Usage

sim.NormalIG.Hierarchical.config(
  nR = 5,
  nC = 100,
  modalityID = c("testA", "testA*"),
  C_dist = "normal",
  mu = 0,
  tau_A = 0,
  tau_B = 0,
  alpha_R = 10,
  beta_R = 1,
  sigma_C = 1,
  a_C = 0.8,
  b_C = 3,
  sigma_tauC = 1,
  alpha_tauR = 10,
  beta_tauR = 1,
  C_scale = 1,
  RC_scale = 1,
  tauC_scale = 1,
  tauRCE_scale = 1
)

Arguments

nR	[num] Number of readers. Default nR = 5
nC	[num] Number of cases. Default nC = 100
modalityID	[vector] List of modalityID. Default modalityID = c("testA", "testA*")
C_dist	[chr] Distribution of the case. Default C_dist="normal"
mu	[num] grand mean. Default mu = 0
tau_A	[num] modality A effect. Default tau_A = 0
tau_B	[num] modality B effect. Default tau_B = 0
alpha_R	[num] shape parameter for reader. Default alpha_R = 10
beta_R	[num] scale parameter for reader. Default beta = 1
sigma_C	[num] std of case factor (if C_dist="normal"). Default sigma_C = 1
a_C	[num] alpha for distribution of case (if C_dist="beta"). Default a_C = 0.8
b_C	[num] beta for distribution of case (if C_dist="beta"). Default b_C = 3
sigma_tauC	[num] std of modality-case (if C_dist="normal"). Default sigma_tauC = 1
alpha_tauR	[num] shape parameter for modality-reader. Default alpha_tauR = 10
beta_tauR	[num] scale parameter for modality-reader. Default beta_tauR = 1
C_scale	[num] weight for the case factor. Default C_scale = 1
RC_scale	[num] weight for the reader-case interaction term. Default RC_scale = 1
tauC_scale	[num] weight for the modality-case term. Default tauC_scale = 1
tauRCE_scale	[num] weight for the modality-reader-case-replicate interaction term. Default tauRCE_scale = 1

Details

If no arguments, this function returns a default simulation configuration for the sim.NormalIG.Hierarchical function.

Value

config [list] of input parameters for sim.NormalIG.Hierarchical.
