Hi,
I would like to use nlexperiment to fit a Netlogo model to data. I am able to run the model, do a sensitivity analysis etc. but as soon as I tried to use optim or nmkb I run into troubles with my…

Hi Yixuan. Do you think it would be possible to make a version where the gradient could be estimated numerically? I am trying to optimise the parameters of the covariance functions (kernels) in a Gaus…

I found, that optimizer for `_fit` was changed from `minimize` to `fmin` in utils with [that commit](https://github.com/CamDavidsonPilon/lifetimes/commit/bc06a6c73932e888c034df1c6a596ca28375e728#diff-…

Dear Mark,
I have been trying to use `rstpm2` to estimate models with shared frailty terms:
