In probability and statistics, the Log Series Distribution is a discrete probability distribution derived from the Maclaurin series expansion.

The Log Series Distribution app provides for the data entry of two variables: Number of Trials and a Probability Parameter. The range for the Number of Trials variable is 1.0 - 12.0 and the range of the Probability Parameter is 0.01 - 0.99.

The Log Series Distribution app produces a PDF/CDF Graph and PDF/CDF Data Tables The Number of Trials and Probability Parameter variables selected are used to compute the PDF/CDF data.

The PDF and CDF graphs are touch interactive graphs for computed (x/Pr(x) paired values. The graphs hav a touch feature whereby upon the touch a slidable vertical line appears. Upon movement of the line a paired (x,Pr(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 Pr(X) values.

Horizontal Max and Min dashed lines display the Maximum and Minimum Pr(x) values
