Research in the software industry on the cone of uncertainty stated that in the beginning of the project life cycle (i.e. before gathering of requirements) estimates have in general an uncertainty of factor 4 on both the high side and the low side. [3] This means that the actual effort or scope can be 4 times or 1/4 of the first estimates.

The cone of uncertainty used by the National Hurricane Center has shrunk dramatically since 2003 as forecasting science improves. Every year, it’s recalculated based on tracking errors from the ...
In linear algebra, a power cone is a kind of a convex cone that is particularly important in modeling convex optimization problems. [1] [2] It is a generalization of the quadratic cone: the quadratic cone is defined using a quadratic equation (with the power 2), whereas a power cone can be defined using any power, not necessarily 2.
