HypoTestInverterResult class holds the array of hypothesis test results and compute a confidence interval.

Based on the RatioFinder code available in the RooStatsCms package developed by Gregory Schott and Danilo Piparo Ported and adapted to RooStats by Gregory Schott Some contributions to this class have been written by Matthias Wolf (error estimation)

Member Function Documentation

◆ Add() [1/2]

bool HypoTestInverterResult::Add ( const HypoTestInverterResult & otherResult )

merge with the content of another HypoTestInverterResult object

Merge this HypoTestInverterResult with another HypoTestInverterResult passed as argument The merge is done by combining the HypoTestResult when the same point value exist in both results.

If results exist at different points these are added in the new result NOTE: Merging of the expected p-values obtained with pseudo-data. When expected p-values exist in the result (i.e. when rebuild option is used when getting the expected limit distribution in the HYpoTestInverter) then the expected p-values are also merged. This is equivalent at merging the pseudo-data. However there can be an inconsistency if the expected p-values have been obtained with different toys. In this case the merge is done but a warning message is printed.

get Limit value corresponding at the desired nsigma level (0) is median -1 sigma is 1 sigma

Get the expected upper limit nsig is used to specify which expected value of the UpperLimitDistribution For example.

nsig = 0 (default value) returns the expected value
nsig = -1 returns the lower band value at -1 sigma
nsig + 1 return the upper value
opt is an option specifying the type of method used for computing the upper limit
opt = "" (default) : compute limit by interpolating all the p values, find the corresponding limit distribution and then find the quantiles in the limit distribution ioption = "P" is the method used for plotting. One Finds the corresponding nsig quantile in the p values and then interpolates them
