Approximations to Error Functions

IEEE Instrumentation & Measurement Magazine, 2007
This paper addresses approximations to error functions and points out three representative approximations, each with its own merits. Cody's approximation is the most computationally intensive of the three, it is not overly so, and there is no arguing over its accuracy.

Asymptotic Approximations and Error Bounds

SIAM Review, 1980
The purpose of this paper is to demonstrate that well-constructed error bounds for asymptotic approximations can provide useful analytical insight into the nature and reliability of the approximati...

Error of normal approximation

Siberian Mathematical Journal, 1984
For a sum of centered independent random vectors \(X_1, X_2,\ldots\); \(E| X_i|^3 \leq L\), \(E| X_i|^2 \leq 1\) taking values in the space \(\ell_{2k}\) \((k\) is natural) with a common covariance operator and \(Y\) a Gaussian centered random vector in \(\ell_{2k}\) with the same covariance operator the following result is proved: \[ P\{| a+S_n|

Approximation Error and Error Accumulation for the Landen Transform

Reliable Computing, 1997
This paper contains a priori error bounds for the approximation error and error accumulation of the descending Landen transform. These results apply to an incomplete elliptic integral of the first kind and give the framework to calculate error bounds in the representation of Jacobi's zeta- and theta-function.

Error of Approximation

2001
In this chapter we will be interested in determining the error d(x, K) made in approximating the element x by the elements of a convex set K. We have already given an explicit formula for the distance d(x, K) in the last chapter (Theorem 6.25), and a strengthening of this distance formula in the particular case where the convex set K is either a convex

Reducing CVBEM Approximation Error

1987
In the previous chapters, the complex variable boundary element method (CVBEM) is used to develop an approximation function \(\hat{\omega }\left( z \right)\) which is analytic in the interior of the region Ω ⋃ Γ I P, where the boundary Γ is a simply connected contour.

Error Estimates in Padé Approximation

1988
Let f be a formal power series $$ f(t) = c_0 + c_1 t + c_2 t^2 + \cdots . $$ We are looking for a rational function whose series expansion in ascending powers of the variable t coincides with that of f as far as possible.

Error Bounds for Stationary Phase Approximations

SIAM Journal on Mathematical Analysis, 1974
An error theory is constructed for the method of stationary phase for integrals of the \[I(x) = \int_a^b {e^{ixp(t)} q(t)dt.} \]Here x is a large real parameter, the function $p(t)$ is real, and neither $p(t)$ nor $q(t)$ need be analytic in t. For both finite and infinite ranges of integration, explicit expressions are derived for the truncation errors
