The Incomplete Beta Function is a standard probability function
For Data Entry the Incomplete Beta Function app utilizes three
data input fields.
The first data field enters the Shapea Parameter. The second data field enters and Shapeb Parameter. The third data field enter the (x) Percentile Parameter.
For the Incomplete Beta Function App graph the horizontal axis displays a range for the (x) value and the vertical axis displays the β(a,b,x) values
The graph is a touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the point β(a,b,x) and the Incomplete Gamma data pairs.
The horizontal x-axis displays x values. The vertical y-axis plots a range of either the x-increment or y-increment values
Horizontal Max and Min dashed lines display the Maximum and Minimum values.
