Chebyshev center

In geometry, the Chebyshev center of a bounded set having non-empty interior is the center of the minimal-radius ball enclosing the entire set , or alternatively (and non-equivalently) the center of largest inscribed ball of . In the field of parameter estimation, the Chebyshev center approach tries to find an estimator for given the feasibility set , such that minimizes the worst possible estimation error for x (e.g. best worst case).

Advice for research mathematicians | The joy of maxel number theory: Chebyshev polys I | Wild Egg

We are advocating a larger view of number theory which goes from arithmetic with numbers to polynumbers to maxels. In this lecture we have a look at the Chebyshev polynumbers of the first kind from this larger linear algebraic point of view. Some surprises are in store! ******************

Statistics - 3.2.2 Empirical Rule and Chebyshev's Theorem

We continue section 3.2 by discussing the Empirical rule used for normal data. We can determine the data values in which we can find 68% of our data, 95% of our data or 99.7% of our data. We also look at Chebyshev's Theorem which gives us similar values for non-normal data. Power Point:

Spread polynomials arise in Rational Trigonometry as variants of the Chebyshev polynomials of the first kind. However the spread polynomials arise in a purely algebraic setting, without any need for appeal to "transcendental functions" which can't actually be evaluated -- such as cos x or
