WebIn case of a Weibull regression model our hazard function is. h ( t) = γ λ t γ − 1. where. λ = exp ( α + β 1 x f e m a l e + β 2 x a g e). 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. 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.
