Linear curve fitting with errors I was looking for a way to perform a linear curve fit in Javascript. I found several libraries, but they don't propagate errors. What I mean is, I have data and associated measurement errors, like: Wh... ...

In total, the example problems included 19 rule-based models defined in BNGL, nine of which were fit to experimental data; nine manually formulated ODE models defined in SBML, 6 of which were fit to experimental data; and 3 problems using closed-form functions. All the problems could be ...
