|LNP3 - Log Normal Probability Plotting Positions
LNP3 is a software tool that computes and plots data in a log normal probability paper.
Probability plots are useful tools for the display and analysis of lifetime data.
Probability plots use an inverse distribution scale so that a cumulative distribution
function plots as a straight line. A nonparametric estimate of data will plot
approximately as a straight line, thus providing a visual assessment of goodness-of-fit.
LNP3 will either plot your x,y data or calculate them using one of the following
methods: Weibull, California, Cunnane, Gringorten and Hazen.
LNPP allows the user to customize the paper in the following aspects: Orientation of
the paper, number of cycles, density of the grid, color of lines and frequency of labels.
In addition the program can fit the data using least squares and find specific values.
The user can enhance the plot presentation by adding texts, points and lines.
The data is input by typing it directly into LNP3 or by copy-paste from other
LNP3 is a beta freeware tool. This program doesn't need to be
installed, just run it.
LNP3.zip contains the executable file (LNP3.exe) and an example
(example.LNP). The steps to use it are very simple; if you have any
problem just send me an e-mail.
