likeParamNames function

Likelihood parameter names

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.

likeParamNames(like.form)

Arguments

• like.form: A text string naming the form of the likelihood.

Returns

A vector of parameter names for that likelihood

Details

For user defined functions, ensure that the user defined start-limits function named .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
