integral- the result of a mathematical integration; F(x) is the integral of f(x) if dF/dx = f(x) figuring,reckoning,calculation,computation- problem solving that involves numbers or quantities indefinite integral- the set of functions F(x) + C, where C is any real number, such that F...
The estimation of γ=∫ ∞∞ 2(x)dx, important in nonparametric inference, is discussed. Methods, based on either density estimators or on the lengths of nonparametric confidence intervals, are compared. We conclude that density type estimators have advantages over the estimators based on confidence...
