We offer development, consulting, and support … WebEfficient methods for optimizing the objective function are based on derivatives, which typically are approximated numerically using finite differences, or alternatively by evaluating an analytical expression for the derivatives. The former method can be unstable, and is inefficient when there are many parameters. Weboptim can be used recursively, and for a single parameter as well as many. It also accepts a zero-length par, and just evaluates the function with that argument. The control argument is a list that can supply any of the following components: trace Non-negative integer.
