EDPcalc

Although you’re more than sure an activity successfully reaches the end, you might end up in failure because of unforeseen variables. A chance to get an idea in advance is to calculate probability. You can easily do this on a computer with the help of applications like EDPcalc.

With no installation required, the application is good to go from the moment download is done. As such, you can store it on a thumb drive so you carry it around in case you want to use it on other computers. Registry entries are not modified during runtime, so there’s no need to worry that overall stability is affected.

The visual design is minimalistic and lets individuals of all levels of experience quickly get the hang of things. Most of the space is covered with input and output fields fitted with corresponding description tags, as well as controls to start calculus, clear a field, or all of them at once.

Probability relies on two input values, namely pretest probability, and likelihood ratio. This simple calculus is also studied in math courses. Although likelihood ratio can be almost any number, pretest probability needs to be a value between 0 and 1. Result is also delivered in decimals between 0 and 1, which means the closer it is to 1, the more chances of success.

The end probability is displayed at the press of a button. Exporting, however, needs to be manually done by copying the value from its field, because there’s no possibility to save to file. What’s more, it would have been useful to be able to calculate probability for a series of event, and have a large log exported.

Taking everything into consideration, we can state that EDPcalc is a useful application which can either help you make decisions, or get an idea of how an ongoing project ends up based on different input values. It’s lightweight, and can be used on the go with little effort.
