Radioactive Waste

Material that is no longer useful and contains radioactive substances at concentrations or levels that require regulatory control.

Logistic Regression

A statistical method for analyzing datasets in which there are one or more independent variables that determine an outcome. The outcome is measured with a dichotomous variable (in which there are only two possible outcomes).

Success

The achievement of a goal, target, or desired outcome, often measured by specific criteria or standards in various contexts.

Confidence Interval

A range of values, derived from sample statistics, that is likely to contain the value of an unknown population parameter with a certain degree of confidence.
