Disclaimer: I have no idea.

Background is that son is forced to observe how some parasitic wasps behave under the influence of some «chemical» insecticides vs. some «biological stuff». In other words and very simplified: Watch when they die and plot it.

The uninitiated may take a look at Kaplan-Meier Estimator.

The stuff is currently done less or more in R which is considered being pain in the ass.

Thanks for any inspiration. Regards, Karl

Update: Thanks to all for the kind replies for my somehow undef question. See also:
