Hi,
I have a problem with solve. I need to define this function b of two variables, which is implicitly defined. I need it later to enter it into some other really nasty equations, which then again have to be solved numerically. So I wanted to define a grind of x and ss and then use an interpolation to get a smooth function version of b. However, I cannot even get a solution at a single point. (Maple does that without problems, so it shouldn't be a mathematical problem, but more of my stupidity). Below find the code an error text. If I use "NSolve" I even get no output. Any ideas?
Best

b[x_, ss_] := Solve[b == x - ss*Quantile[NormalDistribution, b], b, Reals]
b[0.3,0.1]
Solve::inex: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help.
