Hi All I'm trying to get a distribution from an interpolated function but with no success. (*Creating Dist from interpolation*) ff = Interpolation[Table[{i, 1 + RandomReal[1]}, {i, 0, 10, 1}], Method -> "Spline"]; dist = ProbabilityDistribution[ff[x], {x, 0, 10}]; (*Plot Interpolation ok!*) Plot[ff[x], {x, 0, 10}] (*Plot Dist ok!*) Plot[Evaluate@PDF[dist, x], {x, 0, 10}] (*do not work as spected, the histogram don't have the curve format*) randonData = RandomVariate[dist, 100000]; Histogram[randonData, {0.1}, "Probability", PlotRange -> {{0, 10}, All}] tks in advance Murta
