likeParamNames: Likelihood parameter names

In Rdistance: Density and Abundance from Distance-Sampling Surveys

Likelihood parameter names

Description

Returns names of the likelihood parameters. This is a helper function and is not necessary for estimation. It is nice to label some outputs in Rdistance with parameter names like "sigma" or "knee", depending on the likelihood, and this routine provides a way to do that.

Usage

likeParamNames(like.form)

Arguments

like.form

A text string naming the form of the likelihood.

Details

For user defined functions, ensure that the user defined start-limits function named <likelihood>.start.limits can be evaluated on a distance of 1, can accept 0 expansions, a low limit of 0 a high limit of 1, and that it returns the parameter names as the $names component of the result. That is, the code that returns user-defined parameter names is, fn <- match.fun( paste0(like.form, ".start.limits")); ans <- fn(1, 0, 0, 1); ans$names

Value

A vector of parameter names for that likelihood
