EDPcalc

EDPcalc is a handy tool that helps you calculate probabilities. Even if you think everything's in place for an activity to succeed, sometimes unexpected things can pop up and throw a wrench in the works. That’s where EDPcalc steps in, letting you get an idea of the chances ahead of time.

Easy to Use and Portable

The best part? You don’t need to install anything! Once you download EDPcalc, it’s ready to go. You can save it on a thumb drive, making it super easy to use on different computers. Plus, it won’t mess with your computer's registry while running, so no worries about stability issues.

User-Friendly Design

The design is really simple and clean. It’s made so that anyone—whether you're a pro or just starting out—can figure it out quickly. Most of the screen is filled with input and output fields that have easy-to-understand labels. You’ll also find buttons to start calculations or clear your entries when needed.

Understanding Probability

To calculate probability, you'll need two key pieces of info: pretest probability and likelihood ratio. This math is pretty basic and usually covered in school. Just remember, while the likelihood ratio can be any number, pretest probability should be between 0 and 1. The results will come back as decimals too; if it's closer to 1, you've got better chances!

Quick Results but Manual Export

You get your final probability with just one button press! However, if you want to save that result, you'll have to copy it manually since there isn’t an option to save it directly as a file. It would be awesome if you could calculate probabilities for multiple events at once and export a log.
