Description
|
|
•
|
The ProbabilityPlot command generates a probability-probability plot of the user-defined theoretical distribution (on the horizontal axis) against the response values (on the vertical axis). The response values will be sorted, unless otherwise specified (see sorted option). A random sample of the theoretical distribution, having size equal to the size of data will be generated, sorted ascendingly, and plotted against the (ordered) response values.
|
•
|
The first parameter, A, specifies the response values that correspond to the y-coordinates of the points in the plot. A copy of the response values is sorted ascendingly in the function (i.e. if sorted is false as it is by default), and is plotted against a sorted random sample of the given theoretical distribution that correspond to the x-coordinates of the plot.
|
•
|
The second parameter, X is the theoretical distribution or the corresponding random variable.

|
Options
|
|
|
The options argument can contain one or more of the options shown below. All unrecognized options will be passed to the plots[display] command. See plot[options] for details.
|
|
This option specifies colors for the points and for the reference line. When a list of colors is given, the set of points and the reference line will be colored with the corresponding colors in the list.
|
|
If reference is set to true, the reference line will be drawn in the same plot. Default value is true.
|
|
If sorted is set to true, a sorted (ascending) copy of data is used. Otherwise, if false the original data is used. Default value is false.

|
|
Plot it against the same probability distribution.
>
|
|
Plot it against a different distribution. This is the command to create the plot from the Plotting Guide.
