| I don't know what you mean by "slow". The following works after about 60 seconds: dist = TransformedDistribution[Abs[a - b] + Abs[u - v], {a \[Distributed] UniformDistribution[], b \[Distributed] UniformDistribution[], ... |
| While it's annoying to get error messages that aren't easily interpreted, if your data was from biological data that I typically deal with, I'd say you have no peaks as the minor fluctuations that appear look more like random noise. Are the... |
| I think there are potentially 3 things to change: 1. `P` should be a number between 0 and 1. 2. `Fisher2Math` should be `Fisher2Math[k_, p_] := {k, (1 - p)/p}` 3. `Grille` should not include 0 and 1 and should be `Grille = Range[0.05, 0.95,... |
| It would be help (in fact, essential) that you produce the code you used for at least `NonlinearModelFit`. Generally when fitting sine waves to data with `NonlinearModelFit`, there needs to be a reasonable guess at the parameter representing the... |
| Setting values for $b$ and $h$ results in warnings that the integration doesn't converge on $(0,\infty)$. Here's an example: Integrate[Sinh[x]/((Cosh[x] + Cosh[b])*(h^2 - x^2)) /. {h -> 1, b -> 1}, {x, 0, \[Infinity]}] > Integrate::idiv:... |
| The result for any positive integer `n` is the sum of two terms: (1) an `Exp[x y]` term multiplied by a polynomial in `x` and `y` and (2) a polynomial in `x` and `y'. The first term is Exp[x y] LaguerreL[n, (x - y)^2]/n! but I haven't... |
| Gianluca: It's when each of those terms are multiplied by an unassigned symbolic value where the automatic simplification does not occur. |
| My speculation about the appearance of complex numbers is that *Mathematica* uses the pdf of `1/(1/s+1/t)` which contains logs: dist = TransformedDistribution[1/(1/s + 1/t), {t \[Distributed] UniformDistribution[{-1, 1}], s... |

| Maybe I'm misunderstanding the OP's question. I interpret it that there are 4 persons showing up for dinner but you only have 3 chairs to seat them at a round table. I think the question is to generate all possible seating arrangements (with just 3... |
