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.
likeParamNames(like.form)A vector of parameter names for that likelihood
A text string naming the form of the likelihood.
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
