Interactive graph of cdf (or pdf) for many probability distributions
Syntax
Description
The disttool command displays a graphic user interface for exploring the effects of changing parameters on the plot of a cdf or pdf. Clicking and dragging a vertical line on the plot allows you to interactively evaluate the function over its entire domain.
Evaluate the plotted function by typing a value in the x-axis edit box or dragging the vertical reference line on the plot. For cdfs, you can evaluate the inverse function by typing a value in the y-axis edit box or dragging the horizontal reference line on the plot. The shape of the pointer changes from an arrow to a crosshair when it is over the vertical or horizontal line to indicate that the reference line is draggable.
To change the distribution function, choose an option from the menu of functions at the top left of the figure. To change from cdfs to pdfs, choose an option from the menu at the top right of the figure.
To change the parameter settings, move the sliders or type a value in the edit box under the name of the parameter. To change the limits of a parameter, type a value in the edit box at the top or bottom of the parameter slider.
To close the tool, press the Close button.
