model.end {Zelig}R Documentation

Cleaning up after optimization

Description

The model.end function creates a list of regression output from optim output. The list includes coefficients (from the optim par output), a variance-covariance matrix (from the optim Hessian output), and any terms, contrasts, or xlevels (from the model frame). Use model.end after calling optim, but before assigning a class to the regression output.

Usage

model.end(res, mf)

Arguments

res

the output from optim or another fitting-algorithm

mf

the model frame output by model.frame

Value

A list of regression output, including:

coefficients

the optimized parameters

variance

the variance-covariance matrix (the negative inverse of the Hessian matrix returned from the optimization procedure)

terms

the terms object. See terms.object for more information

...

additional elements passed from res
