QuantilePlot

QuantilePlot[data1, data2]
creates a quantile-quantile plot from the real-valued vectors data1 and data2.
  • QuantilePlot plots empirical quantiles of the two vectors against each other.
  • QuantilePlot sorts the shorter dataset, and then determines interpolated quantiles at the equivalent position in the longer list of data.
  • For datasets of equal length, QuantilePlot yields the equivalent of plotting the sorted lists against each other.
  • QuantilePlot has the same options as Graphics, with the following additions and changes:
AxesTruewhether to draw axes
PlotMarkersAutomaticmarkers for points
ReferenceLineStyleAutomaticstyle for the reference line
  • The reference line has a slope of unity. If the points on the plot fall mostly on or near the reference line, the distributions are roughly the same.
