Detailed Description

This class defines an (X,Y) with any number of error sources.

Sources that can be specified are

  • 1 set Statistical errors
  • N sets of common systematic errors
  • M sets of point-to-point systematic errors.

Systematic errors can be defined to relative to the point value or absolute numbers.

There are various options for drawing this data set (see Draw). A function can also be fitted to the data set, talking various kinds of errors into consideration (see Fit). The data set can be export to a format more or less acceptable by the Durham database (see Export), and one can import data sets from Durham database input formatted files (see Import)

Double_t GraphSysErr::MeanX ( Double_t error,

Calculate the mean along X. The strategy used here is the same as for TH1::GetMean - that is the weighted average using the Y values as weights.

If both the mean and standard deviation are needed, one can use the function StatisticsX directly, and calculate the errors as outlined there.

Parameters
errorOn return, the error on the mean
cmnIf true, use common uncertainties
statIf true, use statistical errors
quadIf true, add in quadrature
Returns

static Double_t GraphSysErr::Round ( Double_t  v,
Int_t  p,

inlinestatic

Round number v to n significant digits. It returns the mantisa and the exponent. To calculate the number, do

Int_t e = 0;
Double_t m = Round(v,n,e);
Double_t x = m * TMath::Power(10,e);

If one has a value x and and associated error dx, one can use this function to format the pair:

Int_t e = 0;
Double_t m = Round(dx,n,e);
Double_t p = m * TMath::Power(10,e);
Int_t o = TMath::Ceil(TMath::Log10(TMath::Abs(x)))-e;
std::cout << std::setprecision(o) << x << " +/- "
<< std::setprecision(n) << p << std::endl;

For asymmetric errors, this would be

Int_t el, eh;
Double_t ml = Round(dxl,n,el);
Double_t m2 = Round(dxh,n,eh);
Int_t ne = TMath::Min(el, eh);
Double_t pl = ml * TMath::Power(10,el);
Double_t ph = mh * TMath::Power(10,eh);
Int_t o = TMath::Ceil(TMath::Log10(TMath::Abs(x)))-ne;
std::cout << std::setprecision(o) << x << " -"
<< std::setprecision(n) << pl << " +"
<< std::setprecision(n) << ph << std::endl;
Parameters

inlinestaticprotected

Round number. tens is the scaling divisor to convert tmp into an integer with n significant digits.

The algorightm looks at the n+1 significant digit d, and depending on the value of that, it does one of the following:

  • if d > 5, it rounds the number up
  • if d < 5, it rounds the number down.
  • if d = 5, then the n+2 significant digit dd is investigated.
    • if dd = 0 then the number is rounded up nearest even number
    • if dd != 0 the the number is rounded down
Parameters
tensThe scaling of the number to integer
tmpThe absolute value of the number
Returns
The rounded number

The errors on \(\bar{x}\) and \( s_x\) is given by

\({eqnarray} \delta\bar{x} &=& s_x/n\\ \delta s_x &=& s_x/(\sqrt{2}n)\\ \){eqnarray}

Note
The variable passed for meanX must have the value inf (use TMath::Infinity()) to get the calculated mean back. Any other value will be taken as the mean for the reminder of the calculaitions. This is useful if one wants to calculate the standard deviation around some pre-determined mean rather than the sample mean.
