likeParamNames: Likelihood parameter names

In Rdistance: Distance-Sampling Analyses for Density and Abundance Estimation

Likelihood parameter names

Description

Returns names of the likelihood parameters. This is a helper function and is not necessary for estimation. It is a 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
