I use FrequentistCalculator to get the attached plot. I am having two questions hope you could help:
- the -2sigma error band is quite spiky, any nice way to reduce the spikes ? I have already used about 3000 toys for each mu.
- I was thinking on the plot, from left to right the first intersecting point (of the lower boundary of the -2sigma band) with the line (p-value=0.05) would be the same as the number returned from the function GetExpectedUpperLimit(-2), but I find this is not the true. Any one knows why, and how to properly associate the numbers returned from the GetExpectedUpperLimit(int) and the intersecting points on the plots?
