R: Create a list of perturbed parameters

perturb.params {emdbook} | R Documentation

## Create a list of perturbed parameters

### Description

Takes a baseline set of parameters and perturbs it to create a variety of starting points for maximum likelihood estimation or MCMC

### Usage

    perturb.params(base, alt, which, mult = FALSE, use.base = TRUE)

### Arguments

`base` | a named list (or vector) of parameters
`alt` | a list of lists (or vectors) of alternative parameter values or multipliers
`which` | which parameters to perturb (currently unused)
`mult` | (logical) multiply baseline values rather than replacing them?
`use.base` | (logical) include baseline parameters in the list?

### Details

Takes the baseline parameter list and substitutes alternative values.

### Value

A list of named lists of parameters.

### Note

To be extended.

### Author(s)

Ben Bolker

### Examples

    perturb.params(list(x=1,y=2,z=3),alt=list(x=c(2,4),z=5))
