Expanded Replacement and Extension of the 'optim' Function
Provides a replacement and extension of the optim()
function to call to several function minimization codes in R in a single
statement. These methods handle smooth, possibly box constrained functions
of several or many parameters. Note that function 'optimr()' was prepared to
simplify the incorporation of minimization codes going forward. Also implements some
utility codes and some extra solvers, including safeguarded Newton methods.
Many methods previously separate are now included here.

Provides both parametric and non-parametric estimates of the
correlates of some desired
outcome (e.g. test scores, income) using a new method proposed by
Danieli, Devi and Fryer (2019). This method relaxes the assumption
that one can alter individual characteristics in any way the data
suggest is optimal, and so can be used anytime one wants to use observational
data to better optimize social experiments designed to increase some desired
outcome.
