comment Linear or Non-Linear Model
@dsforecast i don't understand why you need them separately - whoever modeled these separately likely wrote down conditions allowing you to determine these once $\delta$ has been found from the linear regression. Generally, you take $\beta \equiv 1$ to avoid the problem, but you have a specific problem here and it's details must be used.

comment Poisson counting process question, but correct answer not obtained by usual method
@DOGOFWALLSTREET because knowing what happened over a large interval influences information you know about its subintervals.

$P(A|B) \neq P(B|A)$, even here

comment Way to compare three numbers with an algorithm.
+1. I like accounting for relative distances, which my answer does not do. Unfortunately, won't generalize too well. Perhaps you need to divide this by the average instead of the median... Another question to think about is 0, 10, 10.001 are not close (OP's second example) but your metric would be fairly small...

comment Way to compare three numbers with an algorithm.
For OP's examples, $\sigma$ would be small in the first one and large in the second one. Whether he wants to account for relative (like in your answer) or absolute (like in my answer) scales, is not clear from the question...

comment What is $\int \frac{e^{a x}}{1+x^2} dx $?
one iteration by parts will convert this to $\int e^{ax} \tan^{-1}(x)dx$ but not sure this is simpler...

you likely mean $x=-2$ not $x=2$?
