Logistic Distribution Function Calculator for iOS

Upgrade to IOS 9.2Existence of 1 Data Input Field for the (x) variable and 2 data results fields f(x) for the Logistic Probability Density Function and F(X) the Lower Cumulative Density FunctionUpon entering the Compute button x(f(x) and (x/F(x)) data pairs are computed. In addition to being graphed these paired values are displayed in the PDF graph and CDF data tables.An improved touch interactive graph for computed (x/F(x)paired values for the CDF graph. The graph has a touch feature whereby upon the touch a slidable vertical line appears. Upon movement of the line a paired (x,F(x) values appear relative to the line position on the graph curve.The horizontal x-axis displays computed (x) values. The vertical y-axis plots a range of F(X) values. Horizontal Max and Min dashed line display the Maximum and Minimum F(x) values
