Probability Distribution Plotter (ProbDistPlot) is a GIU tool which plots statistical distributions commonly used in reliability engineering. The program plots the probability distribution function, the cumulative distribution function and the hazard rate of each distribution. The user can gain a better understanding of the affect the distribution parameters have on the distribution but interactively changing distribution parameters with slides.

ProbDistPlot is also able to create quick and easy figures by allowing multiple distributions to be plotted on the one figure with automatic legend annotations (updating parameter values), latex and tex labels, and export to excel charts, clipboard, jpg, pdf, .mat and the printer. Exporting to excel actually transfers the data into an excel spreadsheet and creates an organic Excel chart which can be further manipulated in Excel.

To download, right click on the below link and click ‘save as’. Run ProbDistPlot1.1x86Setup.exe to install.

This is companion software to the book, O’Connor, A.N, Probability Distributions Used In Reliability Engineering, The Reliability Information Analysis Center, Lexington Park MD, USA, 2011

Source code can be found on the MATLAB File Central. See ‘About’ menu for licensing.
