Asymptotic Estimates K-Level Crossings of a Random Algebraic Polynomial
Abstract
This paper provides asymptotic estimates for the expected number of real zeros and k-level crossings of a random algebraic polynomial of the form
a0(n-1 c 0)1/2 + a1(n-1 c 1)1/2 x + a2(n-1 c 2)1/2 x2 + …+an-1(n-1 c n-1)1/2xn-1,
where aJ (J=0, 1, 2, … , n-1 ) are independent standard normal random variables and k is constant independent of x . It is shown that these asymptotic estimates are much greater than those for algebraic polynomials of the form a0 + a1 x + a2 x2 + … + an-1xn-1 .Full Text:
