...number of events to be expected from a given sample over the next week can be easily estimated from a simple integral. And the total number of these events from all samples, is just the sum of these estimates over all samples. So far, so good (imagine you have a sample of a variety of species of radionuclides all emitting alpha particles with the same energy - so you can't tell from the decay event which species produced the alpha particles). I guess there are two parts of my question. I get a fit of the exponential distribution to each sample using fitdistr(x,"exponential"). I am findi...
