Profile Histogram.
Profile histograms are used to display the mean value of Y and its error for each bin in X. The displayed error is by default the standard error on the mean (i.e. the standard deviation divided by the sqrt(n) ) Profile histograms are in many cases an elegant replacement of two-dimensional histograms : the inter-relation of two measured quantities X and Y can always be visualized by a two-dimensional histogram or scatter-plot; its representation on the line-printer is not particularly satisfactory, except for sparse data. If Y is an unknown (but single-valued) approximate function of X, this function is displayed by a profile histogram with much better precision than by a scatter-plot.
The following formulae show the cumulated contents (capital letters) and the values displayed by the printing or plotting routines (small letters) of the elements for bin J.
2 H(J) = sum Y E(J) = sum Y l(J) = sum l L(J) = sum l h(J) = H(J)/L(J) mean of Y, s(J) = sqrt(E(J)/L(J)- h(J)**2) standard deviation of Y (e.g. RMS) e(J) = s(J)/sqrt(L(J)) standard error on the mean
The displayed bin content for bin J of a TProfile is always h(J). The corresponding bin error is by default e(J). In case the option "s" is used (in the constructor or by calling TProfile::BuildOptions) the displayed error is s(J)
In the special case where s(J) is zero (eg, case of 1 entry only in one bin) the bin error e(J) is computed from the average of the s(J) for all bins if the static function TProfile::Approximate has been called. This simple/crude approximation was suggested in order to keep the bin during a fit operation. But note that this approximation is not the default behaviour. See also TProfile::BuildOptions for other error options and more detailed explanations

| ) |
Normal Constructor for Profile histograms.
The first five parameters are similar to TH1D::TH1D. All values of y are accepted at filling time. To fill a profile histogram, one must use TProfile::Fill function.
Note that when filling the profile histogram the function Fill checks if the variable y is between fYmin and fYmax. If a minimum or maximum value is set for the Y scale before filling, then all values below ymin or above ymax will be discarded. Setting the minimum or maximum value for the Y scale before filling has the same effect as calling the special TProfile constructor below where ymin and ymax are specified.
H(J) is printed as the channel contents. The errors displayed are s(J) if CHOPT='S' (spread option), or e(J) if CHOPT=' ' (error on mean).
See TProfile::BuildOptions for explanation of parameters

In the case of Profile filled weights and with TProfile::Sumw2() called, STD(Y) is the standard deviation of the weighted sample Y and N is in this case the number of effective entries (TProfile::GetBinEffectiveEntries(ibin) )
If a bin has N data points all with the same value Y (especially possible when dealing with integers), the spread in Y for that bin is zero, and the uncertainty assigned is also zero, and the bin is ignored in making subsequent fits. To avoid this problem one can use an approximation for the standard deviation S(Y), by using the average of all the S(Y) of the other Profile bins. To use this approximation one must call before TProfile::Approximate This approximation applies only for the default and the 's' options

Profile histogram is resized along x axis such that x is in the axis range.
The new axis limits are recomputed by doubling iteratively the current axis range until the specified value x is within the limits. The algorithm makes a copy of the histogram, then loops on all bins of the old histogram to fill the extended histogram. Takes into account errors (Sumw2) if any. The axis must be extendable before invoking this function.

Return bin effective entries for a weighted filled Profile histogram.
In case of an unweighted profile, it is equivalent to the number of entries per bin The effective entries is defined as the square of the sum of the weights divided by the sum of the weights square. TProfile::Sumw2() must be called before filling the profile with weights. Only by calling this method the sum of the square of the weights per bin is stored.

Computing errors: A moving field
The computation of errors for a TProfile has evolved with the versions of ROOT. The difficulty is in computing errors for bins with low statistics.
Ideas for improvements of this algorithm are welcome. No suggestions received since our call for advice to roottalk in Jul 2002. see for instance: http://root.cern.ch/root/roottalk/roottalk02/2916.html

Merge all histograms in the collection in this histogram.
This function computes the min/max for the x axis, compute a new number of bins, if necessary, add bin contents, errors and statistics. If overflows are present and limits are different the function will fail. The function returns the total number of entries in the result histogram if the merge is successfull, -1 otherwise.
IMPORTANT remark. The axis x may have different number of bins and different limits, BUT the largest bin width must be a multiple of the smallest bin width and the upper limit must also be a multiple of the bin width.

Rebin this profile grouping ngroup bins together.
if newname is not blank a new temporary profile hnew is created. else the current profile is modified (default) The parameter ngroup indicates how many bins of this have to me merged into one bin of hnew If the original profile has errors stored (via Sumw2), the resulting profile has new errors correctly calculated.
examples: if hp is an existing TProfile histogram with 100 bins
NOTE: If ngroup is not an exact divider of the number of bins, the top limit of the rebinned profile is changed to the upper edge of the bin=newbins*ngroup and the corresponding bins are added to the overflow bin. Statistics will be recomputed from the new bin contents.
a new profile is created (you should specify newname). The parameter ngroup is the number of variable size bins in the created profile The array xbins must contain ngroup+1 elements that represent the low-edge of the bins. The data of the old bins are added to the new bin which contains the bin center of the old bins. It is possible that information from the old binning are attached to the under-/overflow bins of the new binning.

The computation of the bin errors is based on the parameter option:
-' ' (Default) The bin errors are the standard error on the mean of the bin profiled values (Y), i.e. the standard error of the bin contents. Note that if TProfile::Approximate() is called, an approximation is used when the spread in Y is 0 and the number of bin entries is > 0 -'s' The bin errors are the standard deviations of the Y bin values Note that if TProfile::Approximate() is called, an approximation is used when the spread in Y is 0 and the number of bin entries is > 0 -'i' Errors are as in default case (standard errors of the bin contents) The only difference is for the case when the spread in Y is zero. In this case for N > 0 the error is 1./SQRT(12.*N) -'g' Errors are 1./SQRT(W) for W not equal to 0 and 0 for W = 0. W is the sum in the bin of the weights of the profile. This option is for combining measurements y +/- dy, and the profile is filled with values y and weights w = 1/dy**2
See TProfile::BuildOptions for a detailed explanation of all options
