"%lg %lg"
read only 2 first columns into X, Y"%lg %lg %lg %lg"
read only 4 first columns into X, Y, ELY, EHY"%lg %lg %lg %lg %lg %lg"
read only 6 first columns into X, Y, EXL, EYH, EYL, EHYFor files separated by a specific delimiter different from ‘’ 'and
'\t'(e.g.
';'in csv files) you can avoid using
%*sto bypass this delimiter by explicitly specify the
"option" argument, e.g. option=" \\t,;"
for columns of figures separated by any of these characters ‘(’ ', '\t', ',', ';') used once
(e.g. "1;1")or in a combined way
(" 1;,;; 1"). Note in that case, the instantiation is about 2 times slower. In case a delimiter is specified, the format
"%lg %lg %lg"` will read X,Y,EX.

Apply a function to all data points \( y = f(x,y) \).
Errors are calculated as \( eyh = f(x,y+eyh)-f(x,y) \) and \( eyl = f(x,y)-f(x,y-eyl) \)
Special treatment has to be applied for the functions where the role of "up" and "down" is reversed.

This function is only kept for backward compatibility.
You should rather use the Divide method. It calls Divide(pass,total,"cl=0.683 b(1,1) mode")
which is equivalent to the former BayesDivide method.

Fill this TGraphAsymmErrors by dividing two 1-dimensional histograms pass/total.
This method serves two purposes:
The assumption is that the entries in "pass" are a subset of those in "total". That is, we create an "efficiency" graph, where each entry is between 0 and 1, inclusive.
If the histograms are not filled with unit weights, the number of effective entries is used to normalise the bin contents which might lead to wrong results.
\[ \text{effective entries} = \frac{(\sum w_{i})^{2}}{\sum w_{i}^{2}} \]
The points are assigned a x value at the center of each histogram bin. The y values are \(\text{eff} = \frac{\text{pass}}{\text{total}}\) for all options except for the bayesian methods where the result depends on the chosen option.
If the denominator becomes 0 or pass > total, the corresponding bin is skipped.
The two histograms are interpreted as independent Poisson processes and the ratio
\[ \tau = \frac{n_{1}}{n_{2}} = \frac{\varepsilon}{1 - \varepsilon} \]
with \(\varepsilon = \frac{n_{1}}{n_{1} + n_{2}}\). The histogram 'pass' is interpreted as \(n_{1}\) and the total histogram is used for \(n_{2}\).
The (asymmetric) uncertainties of the Poisson ratio are linked to the uncertainties of efficiency by a parameter transformation:
\[ \Delta \tau_{low/up} = \frac{1}{(1 - \varepsilon)^{2}} \Delta \varepsilon_{low/up} \]
The x errors span each histogram bin (lowedge ... lowedge+width) The y errors depend on the chosen statistic methode which can be determined by the options given below. For a detailed description of the used statistic calculations please have a look at the corresponding functions!
Options:
Note: Unfortunately there is no straightforward approach for determining a confidence interval for a given confidence level. The actual coverage probability of the confidence interval oscillates significantly according to the total number of events and the true efficiency. In order to decrease the impact of this oscillation on the actual coverage probability a couple of approximations and methodes has been developed. For a detailed discussion, please have a look at this statistical paper: http://www-stat.wharton.upenn.edu/~tcai/paper/Binomial-StatSci.pdf
