The Beta Function Calculator iphone/ipd/Apple Watch app allows for the input of five data variables: the (x) and (y) data values to calculate the Beta Integral B(x,y) function and the Shape (a), Shape (b) and (x) Percentile Variable to calculate Beta Distribution PDF and CDF values.
Beta Function Calculator also displays a graphs and data tables for a range of 100 x/f(x) data pairs for the PDF and CDF values.
The graphs are touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the point x/f(x)
The horizontal x-axis displays x values. The vertical y-axis plots a range of either the x-increment and y-increment values
Horizontal Max and Min dashed lines display the Maximum and Minimum values.
