Constructor Detail

DiscreteDistIntChart

public DiscreteDistIntChart(DiscreteDistributionInt dist)
Constructor for a new DiscreteDistIntChart instance used to plot the probabilities of the discrete distribution dist over the integers.

Parameters:
dist - discrete distribution to plot

DiscreteDistIntChart

public DiscreteDistIntChart(DiscreteDistributionInt dist,
                            int a,
                            int b)
Constructor for a new DiscreteDistIntChart instance used to plot the probabilities of the discrete distribution dist over the interval [a, b].

Parameters:
dist - continuous distribution to plot
a - lower bound of interval
b - upper bound of interval
Method Detail

viewCdf

public JFrame viewCdf(int width,
                      int height,
                      int a,
                      int b)
Displays a chart of the cumulative distribution function (cdf) over the interval [a, b] on the screen using Swing. This method creates an application containing a chart panel displaying the chart. The created frame is positioned on-screen, and displayed before it is returned. The width and the height of the chart are measured in pixels.

Parameters:
width - frame width in pixels.
height - frame height in pixels.
a - lower bound of interval
b - upper bound of interval
Returns:
frame containing the chart

viewCdf

public JFrame viewCdf(int width,
                      int height)
Similar to method viewCdf above. If the interval [a, b] for the graph is not defined, it will be set automatically to [μ -3σ, μ +3σ], where μ and σ are the mean and the variance of the distribution.

Parameters:
width - frame width in pixels
height - frame height in pixels
Returns:
frame containing the chart

viewProb

public JFrame viewProb(int width,
                       int height,
                       int a,
                       int b)
Displays a chart of the probability mass function over the interval [a, b] on the screen using Swing. This method creates an application containing a chart panel displaying the chart. The created frame is positioned on-screen, and displayed before it is returned. The width and the height of the chart are measured in pixels.

Parameters:
width - frame width in pixels.
height - frame height in pixels.
a - lower bound of interval
b - upper bound of interval
Returns:
frame containing the chart

viewProb

public JFrame viewProb(int width,
                       int height)
Similar to method viewProb above. If the interval [a, b] for the graph is not defined, it will be set automatically to [μ -3σ, μ +3σ], where μ and σ are the mean and the variance of the distribution.

Parameters:
width - frame width in pixels.
height - frame height in pixels.
Returns:
frame containing the chart

setParam

public void setParam(int a,
                     int b)
Sets the parameters a and b for this object.

Parameters:
a - lower bound of interval
b - upper bound of interval

toLatexCdf

public String toLatexCdf(int width,
                         int height)
Exports a chart of the cumulative probability to a LATEX source code using PGF/TikZ. This method constructs and returns a string that can be written to a LATEX document to render the plot. width and height represents the width and the height of the produced chart. These dimensions do not take into account the axes and labels extra space. The width and the height of the chart are measured in centimeters.

Parameters:
width - Chart's width in centimeters
height - Chart's height in centimeters
Returns:
LaTeX source code

toLatexProb

public String toLatexProb(int width,
                          int height)
Similar to toLatexCdf, but for the probability instead of the cdf.

Parameters:
width - Chart's width in centimeters
height - Chart's height in centimeters
Returns:
LaTeX source code

getCdf

public XYLineChart getCdf()
Returns the chart of the cdf.

Returns:
the chart of the cdf.

getProb

public XYLineChart getProb()
Returns the chart of the probability.

Returns:
the chart of the probability.
