RooIntegralMorph Class Reference

Class RooIntegralMorph is an implementation of the histogram interpolation technique described by Alex Read in 'NIM A 425 (1999) 357-369 'Linear interpolation of histograms' for continuous functions rather than histograms.

The interpolation method, in short, works as follows.

• Given a p.d.f f1(x) with c.d.f F1(x) and p.d.f f2(x) with c.d.f F2(x)
• One finds takes a value 'y' of both c.d.fs and determines the corresponding x values x(1,2) at which F(1,2)(x)==y.
• The value of the interpolated p.d.f fbar(x) is then calculated as fbar(alpha*x1+(1-alpha)*x2) = f1(x1)*f2(x2) / ( alpha*f2(x2) + (1-alpha)*f1(x1) ) ;

From a technical point of view class RooIntegralMorph is a p.d.f that takes two input p.d.fs f1(x,p) an f2(x,q) and an interpolation parameter to make a p.d.f fbar(x,p,q,alpha). The shapes f1 and f2 are always taken to be end the end-points of the parameter alpha, regardless of what the those numeric values are.

Since the value of fbar(x) cannot be easily calculated for a given value of x, class RooIntegralMorph is an implementation of RooAbsCachedPdf and calculates the shape of the interpolated p.d.f. fbar(x) for all values of x for a given value of alpha,p,q and caches these values in a histogram (as implemented by RooAbsCachedPdf). The binning granularity of the cache can be controlled by the binning named "cache" on the RooRealVar representing the observable x. The fbar sampling algorithm is based on a recursive division mechanism with a built-in precision cutoff: First an initial sampling in 64 equally spaced bins is made. Then the value of fbar is calculated in the center of each gap. If the calculated value deviates too much from the value obtained by linear interpolation from the edge bins, gap is recursively divided. This strategy makes it possible to define a very fine cache sampling (e.g. 1000 or 10000) bins without incurring a corresponding CPU penalty.

Note on numeric stability of the algorithm. Since the algorithm relies on a numeric inversion of cumulative distributions functions, some precision may be lost at the 'edges' of the same (i.e. at regions in x where the c.d.f. value is close to zero or one). The general sampling strategy is to start with 64 equally spaces samples in the range y=(0.01-0.99). Then the y ranges are pushed outward by reducing y (or the distance of y to 1.0) by a factor of sqrt(10) iteratively up to the point where the corresponding x value no longer changes significantly. For p.d.f.s with very flat tails such as Gaussians some part of the tail may be lost due to limitations in numeric precision in the CDF inversion step.

An effect related to the above limitation in numeric precision should be anticipated when floating the alpha parameter in a fit. If a p.d.f with such flat tails is fitted, it is likely that the dataset contains events in the flat tail region. If the alpha parameter is varied, the likelihood contribution from such events may exhibit discontinuities in alpha, causing discontinuities in the summed likelihood as well that will cause convergence problems in MINUIT. To mitigate this effect one can use the setCacheAlpha() method to instruct RooIntegralMorph to construct a two-dimensional cache for its output values in both x and alpha. If linear interpolation is requested on the resulting output histogram, the resulting interpolation of the p.d.f in the alpha dimension will smooth out the discontinuities in the tail regions result in a continuous likelihood distribution that can be fitted. An added advantage of the cacheAlpha option is that if parameters p,q of f1,f2 are fixed, the cached values in RooIntegralMorph are valid for the entire fit session and do not need to be recalculated for each change in alpha, which may result an considerable increase in calculation speed.
