logLikFn {profileCI} | R Documentation |
Calculate Log-Likelihood
Description
This is a generic function for calculating a log-likelihood for an object at input parameter values.
Usage
logLikFn(object, pars, ...)
## S3 method for class 'glm'
logLikFn(object, pars, ...)
## S3 method for class 'nls'
logLikFn(object, pars, ...)
Arguments
object |
A fitted model object. |
pars |
A numeric vector of parameters of the model. |
... |
Further arguments. None are used in the |
Details
This generic function has been created to enable a function that
calculates the log-likelihood for a parametric model at a given set of
parameter values in pars
to be available to the function profileCI
.
Value
A numeric scalar. The value of the log-likelihood function for the
fitted model object object
for parameter values pars
.
The logLikFn.glm
generic is specifically for the unweighted Poisson
log-linear GLM case.
The logLikFn.nls
generic is more general and should work for all
model objects returned by stats::nls
.
