Re: [R] Optimizing given two vectors of data (confusedSoul)

I am trying to estimate an Arrhenius-exponential model in R. I have one vector of data containing failure times, and another containing corresponding temperatures. I am trying to optimize a maximum likelihood function given BOTH these vectors. However, the optim command takes only one such vect

Re: [R] Optimizing given two vectors of data

Optim uses vectors of _parameters_, not of data. You add a (likelihood) function, give initial values of the parameters, and get the optimized parameters back. See ?optim and the examples therein. It contains an example for optimization using multiple data columns. Cheers Joris On Fri, Jun 25, 20
