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
