Hi, I'm currently doing some analyses on time of failure of a product. I found on the internet some article about the Arrhenius equation, and I can calculate the results with R. Equation: k=A*exp(-Ea/R*T) I can fit a model with lm for this purpose, so far no problem. But for the confidence interval, how can I use the Weibull distribution? Or should I use the weibull distribution at all? Or can I safely use the predict.lm...

hello there, I like to print a theoretical function into my data. It would work with "panel.curve" when it's all "normal". but unfortunately it's an arrhenius plot and I need "1000/Temperature"(70-300K) at the x-axis. With my data it wasn't a Problem but now I have to add this function to the plot and don't know how to turn around the variable in the function and adapt the plot to this. log(n)=log(f(T^.5))-const/T thanks Markus

Hi! How do you guys solve windows security updates? Is there a way to force windows computers to be updated. Even more flexible is if one can update windows through login script.
