◆ Draw()

void LikelihoodIntervalPlot::Draw ( const Option_t * options = nullptr )

override

draw the likelihood interval or contour for the 1D case a RooPlot is drawn by default of the profiled Log-Likelihood ratio if option "TF1" is used the objects are drawn using a TF1 scanning the LL function in a grid of the set points (by default the TF1 can be costumized by setting maximum and the number of points to scan

draw the log of the profiled likelihood function in 1D with the interval or as a 2D plot with the contours.

Higher dimensional intervals cannot be drawn. One needs to call SetPlotParameters to project interval in 1 or 2dim

Options for drawing 1D intervals

For 1D problem the log of the profiled likelihood function is drawn by default in a RooPlot as a RooCurve The plotting range (default is the full parameter range) and the precision of the RooCurve can be specified by using SetRange(x1,x2) and SetPrecision(eps). SetNPoints(npoints) can also be used (default is npoints=100) Optionally the function can be drawn as a TF1 (option="tf1") obtained by sampling the given npoints in the given range

Options for drawing 2D intervals

For 2D case, a contour and optionally the profiled likelihood function is drawn by sampling npoints in the given range. A 2d histogram of nbinsX=nbinsY = sqrt(npoints) is used for sampling the profiled likelihood. The contour can be obtained by using Minuit or by the sampled histogram, If using Minuit, the number of points specifies the number of contour points. If using an histogram the number of points is approximately the total number of bins of the histogram. Possible options:

minuit/nominuit: use minuit for computing the contour
hist/nohist : sample in an histogram the profiled likelihood

Note that one can have both a drawing of the sampled likelihood and of the contour using minuit. The default options is "minuit nohist" The sampled histogram is drawn first by default using the option "colz" and then 8 probability contours at these CL are drawn: { 0.1,0.3,0.5,0.683,0.95,0.9973,0.9999366575,0.9999994267} re-drawing the histogram with the option "cont3"

The drawn object (RooPlot or sampled histogram) is saved in the class and can be retrieved using GetPlottedObject() In this way the user can eventually customize further the plot. Note that the class does not delete the plotted object. It needs, if needed, to be deleted by the user
