largest and smallest value taken by the function. Known generically as extremum, they may be defined either within a given range (the local or relative...

In statistics and econometrics, extremum estimators are a wide class of estimators for parametric models that are calculated through maximization (or minimization)...

orthogonal directions are all zero (a critical point), but which is not a local extremum of the function. An example of a saddle point is when there is a critical...

Caryocolum extremum is a moth of the family Gelechiidae. It is found in Nepal. The habitat consists of primary montane oak forests. The length of the forewings...

interior extremum theorem) is a method to find local maxima and minima of differentiable functions on open sets by showing that every local extremum of the...

its first derivative f' has an isolated extremum at x. (this is not the same as saying that f has an extremum). That is, in some neighborhood, x is the...

for finding an extremum (minimum or maximum) of a function inside a specified interval. For a strictly unimodal function with an extremum inside the interval...

at x is concave down; a maximal extremum. If f″(x) > 0, the stationary point at x is concave up; a minimal extremum. If f″(x) = 0, the nature of the...

interval, but not a single point. Accordingly, the necessary condition of extremum (functional derivative equal zero) appears in a weak formulation (variational...
