Detailed Description

class to check if a histogram follows a normal distribution

Member Function Documentation

std::vector< double > stira::common::QuantileNormalDistribution::AnalyseNormalizedHistogram ( std::vector< double >  normalizedHistogram, double &  rho, bool  writeQuantiles = false  )

static

analyse a normalised histogram if its quantiles follow those of a normal distribution If the normalizedHistogram follows a normal distribution, the points in a Quantile-Quantile plot follow a straight line

Parameters

normalizedHistogram	the histogram (expected to be normalized) as input
rho	the correlation coefficient of the quantiles of the input histogram and those of a standard normal dsitribution
writeQuantiles	flag whether or not to write the quantiles

Returns

a vector (a, b) that describes the linear relationship y = ax+b between the normal quantiles and the histogram quantiles
