We consider the convergence rate of sequential fixed-width confidence intervals for [theta]=a[mu]+b[sigma] under a normal model with [mu] and [sigma]2 both unknown. We use the fully sequential procedure proposed by [Takada, Y., 1997. Fixed-width confidence intervals for a function of normal...

In this paper, we consider the estimation of a parameter of interest where the estimator is one of the possibly several solutions of a set of nonlinear empirical equations. Since Newton's method is often used in such a setting to obtain a solution, it is important to know whether the so obtained...

A common practice in protein sequence alignment is to try several scoring matrices until ``something interesting'' is found. This leads to a multiple testing problem making p- and E-values hard to interpret. We focus on local alignment and propose to use logistic copula functions to model...
