You might try FindMinimum where the function you're minimizing is the distance from the curve to the data point when the curve is above the data point and some large value (say, 500) when the curve is below the observed data point (i.e., a penalty for the curve being below the data). But without any mention of how the data is generated in a probabilistic manner, this is just a manipulation of the data without the ability to make statistical inferences.

I don't think the code you've posted does what you intended (I get b being Null). Can you check it?
