WebGeneral-purpose optimization wrapper function that calls other R tools for optimization, including the existing optim() function. optim also tries to unify the calling sequence to allow a number of tools to use the same front-end. Note that optim() itself allows Nelder--Mead, quasi-Newton and conjugate-gradient algorithms as well as box-constrained optimization … Weboptimx-package A replacement and extension of the optim() function, plus various op-timization tools Description optimx provides a replacement and extension of the link{optim()} function to unify and stream-line optimization capabilities in R for smooth, possibly box constrained functions of several or many parameters

Using this more complex hazard function we can fit changes in the hazard across time of follow up. So now let’s get started with loading the data set and setting up the variables. # 1.
