Log-Likelihood of a gnls Object

DESCRIPTION:

Returns the log-likelihood value of the nonlinear model represented by object evaluated at the estimated coefficients.

USAGE:

logLik(object) 

REQUIRED ARGUMENTS:

object
an object inheriting from class gnls, representing a generalized nonlinear least squares fitted model.

VALUE:

the log-likelihood of the linear model represented by object evaluated at the estimated coefficients.

EXAMPLES:

fm1 <- gnls(weight ~ SSlogis(Time, Asym, xmid, scal), Soybean, 
            weights = varPower()) 
logLik(fm1)
