In seroanalytics/serosolver: Inference Framework for Serological Data

MCMC proposal function

Description

Proposal function for MCMC random walk, taking random steps of a given size.

Usage

univ_proposal(
  values,
  lower_bounds,
  upper_bounds,
  steps,
  index,
  gaussian_proposal = TRUE
)

Arguments

values	a vector of the parameters to be explored
lower_bounds	a vector of the low allowable bounds for the proposal
upper_bounds	a vector of the upper allowable bounds for the proposal
steps	a vector of step sizes for the proposal
index	numeric value for the index of the parameter to be moved from the param table and vector
gaussian_proposal	if TRUE, then samples moves from a Gaussian distribution centered around the current value

Value

the parameter vector after step
