Return the objective function

ofv(x, type, ...)

## Arguments

x object to return objective function value Objective function type value to retrieve or add. focei For most models you can specify "focei" and it will add the focei objective function. nlme This switches/chooses the nlme objective function if applicable. This objective function cannot be added if it isn't present. fo FO objective function value. Cannot be generated foce FOCE object function value. Cannot be generated laplace# This adds/retrieves the Laplace objective function value. The # represents the number of standard deviations requested when expanding the Gaussian Quadrature. This can currently only be used with saem fits. gauss#.# This adds/retrieves the Gaussian Quadrature approximation of the objective function. The first number is the number of nodes to use in the approximation. The second number is the number of standard deviations to expand upon. Other arguments sent to ofv for other methods.
