### Measurement error propagation onto fitting-parameters

I have a dataset consisting of (t,y) Tuples, where each y has a known measurement error (standard deviation). I would like to fit a trapaze-function into the data and obtain the fitting paramaters and ...

### How can I define unique epsilons with bounded range for floating point analysis?

I'd like to use Mathematica for analyzing error bounds in floating point code. To do this, we can use the standard model for floating point error: $$flt(a\oplus b) = (a\oplus b)(1+\epsilon_i)$$ Where ...
