Actually if your estimate at a given point is done using an iterative method with some uncertainties on the final value, you might rather look for approximations ie. smoothing interpolations rather then strict interpolations.  
See discussion [Convexity-Preserving Rational Interpolation](https://discourse.julialang.org/t/convexity-preserving-rational-interpolation/79112)

But if your function is not smooth then any interpolation function will probably have trouble unless you have a lot of points.
