Hi, could somebody help me with the following issue?: Regarding the package "Statistics'NonlinearFit", is it possible to fit an array of preexisting data with a function defined by NDSolve? Example: f[y_,a_,b_] :=NDSolve[x'[y] == (y^2/2 + a y + b)/Sqrt[1 -(y^2/2 + a y + b)^2], x[0] == .6}, y, {y, 0, 1.5}]; Thanks in advance! Regards, Lautaro
