proposalfunction1: MCMC proposal function

In jameshay218/mcmcJH: Generic random walk MCMC algorithm for parameter inference

Description

Proposal function for MCMC random walk, taking random steps of a given size. Requires toUnitScale and fromUnitScale from the mathfuncs package. Random walk may be on a linear or log scale

Usage

proposalfunction1(param, param_table, index)

Arguments

param	a vector of the parameters to be explored
param_table	a matrix of flags and bounds that specify how the proposal should be treated. Crucial elements are the 3rd column (lower bound), 4th column (upper bound), 5th column )step size) and 6th column (flag for log proposal)
index	numeric value for the index of the parameter to be moved from the param table and vector

Value

the parameter vector after step
