Estimation/planning tools that support confidence intervals?


Any good estimation tools or project planning tools that allow me to not just define a single number to estimate effort but rather allow more sophisticated ways of estimation such as providing a confidence interval or a mean/derivation combination?

You can play with Guesstimate, a spreadsheet-like tool handling uncertainty.

Here's an example of estimating the duration of a task (shopping): https://www.getguesstimate.com/models/19512
