In santosneto/RBS: Regression models for Birnbaum-Saunders distributions

#'Brown and Miller's biaxial fatigue data

#'Several data sets related to the BS distribution are available in the RBS package, which have been taken from the literature on this topic.

#'@docType data

#'@name biaxial
#'@usage data(biaxial)
#'@format A vector containing 46 observations.
#'@details Rieck and Nedelman (1991) reported a data set from Brown and Miller (1978). These data represent results of fatigue tests on 1 \eqn{\%} Cr-Mo-V steel. Cylindrical specimens were subjected to combined torsional and axial loads over constant-amplitude cycles until failure.
