set_control_sim {RiskMap}R Documentation

Set Control Parameters for Simulation

Description

This function sets control parameters for running simulations, particularly for MCMC methods. It allows users to specify the number of simulations, burn-in period, thinning interval, and various other parameters necessary for the simulation.

Usage

set_control_sim(
  n_sim = 12000,
  burnin = 2000,
  thin = 10,
  h = NULL,
  c1.h = 0.01,
  c2.h = 1e-04,
  linear_model = FALSE
)

Arguments

n_sim

Integer. The total number of simulations to run. Default is 12000.

burnin

Integer. The number of initial simulations to discard (burn-in period, used for the MCMC algorithm). Default is 2000.

thin

Integer. The interval at which simulations are recorded (thinning interval, used for the MCMC algorithm). Default is 10.

h

Numeric. An optional parameter. Must be non-negative if specified.

c1.h

Numeric. A control parameter for the simulation. Must be positive. Default is 0.01.

c2.h

Numeric. Another control parameter for the simulation. Must be between 0 and 1. Default is 1e-04.

linear_model

Logical. If TRUE, the function sets up parameters for a linear model and only returns n_sim. Default is FALSE.

Details

The function validates the input parameters and ensures they are appropriate for the simulation that is used in the glgpm fitting function. For non-linear models, it checks that n_sim is greater than burnin, that thin is positive and a divisor of (n_sim - burnin), and that h, c1.h, and c2.h are within their respective valid ranges.

If linear_model is TRUE, only n_sim and linear_model are required, and the function returns a list containing these parameters.

If linear_model is FALSE, the function returns a list containing n_sim, burnin, thin, h, c1.h, c2.h, and linear_model.

Value

A list of control parameters for the simulation with class attribute "mcmc.RiskMap".
