tensile: The Tensile Data files for GAMLSS

Description

tensile: These data come from Quesenberry and Hales (1980) and were also reproduced in Hand et al. (1994), data set 180, page 140. They contain measurements of tensile strength of polyester fibres and the authors were trying to check if they were consistent with the lognormal distribution. According to Hand et al. (1994) "these data follow from a preliminary transformation. If the lognormal hypothesis is correct, these data should have been uniformly distributed".

Usage

data(tensile)

Format

Data frames each with the following variable.

str

a numeric vector showing the tensile strength
