Detailed Description
This class implements QQ-plot (or quantile-quantile plot) objects that compare two probability distributions.
The data is given as a list of \(x\)-coordinates \((x_1, x_2, …, x_n)\), and one is given a reference continuous probability distribution \(F(x)\). One first sorts the \(x_i\) in ascending order, then noted \(x_{(i)}\), and plots the points \((F^{-1}(p_i), x_{(i)})\), where \(i= 1, 2, …, n\) and \(p_i = (i- 1/2)/n\), to see if the data \(x_i\) comes from the reference distribution \(F(x)\). The graph of the straight line \(y=x\) is also plotted for comparison.
Constructor & Destructor Documentation
◆ QQPlot() [1/3]
| QQPlot | ( | String | title, |
| String | XLabel, | ||
| String | YLabel, | ||
| ContinuousDistribution | dist, | ||
| double [] | X | ||
| ) |
Constructs a new QQPlot instance using the points X.
title is a title, XLabel is a short description of the \(x\)-axis, and YLabel a short description of the \(y\)-axis. The plot is a QQ-plot of the points \((F^{-1}(p_i), x_{(i)})\), \(i= 1, 2, …, n\), where \(p_i = (i- 1/2)/n\), \(x_i = \) X[ \(i\)-1], \(x_{(i)}\) are the sorted points, and \(x = F^{-1}(p) = \) dist.inverseF( \(p\)). The points X are not sorted.
- Parameters
-
title chart title. XLabel Label on \(x\)-axis. YLabel Label on \(y\)-axis. dist Reference distribution X points.
◆ QQPlot() [2/3]
| QQPlot | ( | String | title, |
| String | XLabel, | ||
| String | YLabel, | ||
| ContinuousDistribution | dist, | ||
| double [] | X, | ||
| int | numPoints | ||
| ) |
Similar to the constructor QQPlot(title, XLabel, YLabel, dist, X) above, except that only the first numPoints of X are plotted.
- Parameters
-
title chart title. XLabel Label on \(x\)-axis. YLabel Label on \(y\)-axis. dist Reference distribution X point set. numPoints number of points to plot
◆ QQPlot() [3/3]
| QQPlot | ( | String | title, |
| String | XLabel, | ||
| String | YLabel, | ||
| ContinuousDistribution | dist, | ||
| double | data[][], | ||
| int | r | ||
| ) |
Constructs a new QQPlot instance.
title is a title, XLabel is a short description of the \(x\)-axis, and YLabel a short description of the \(y\)-axis. The input vectors in data represents several sets of \(x\)-points. \(r\) determine the set of points to be plotted in the QQ-plot, that is, one will plot only the points data[r][i], for \(i=0, 1, …, (n-1)\) and a given \(r\), where \(n\) is the number of points in set \(r\). The points are assumed to follow the distribution dist.
- Parameters
-
title chart title. XLabel Label on \(x\)-axis. YLabel Label on \(y\)-axis. dist Reference distribution data series of point sets. r set of points to plot
