The Birnbaum–Saunders (BS) distribution, also known as the fatigue life is right-skewed and used to model failure times of industrial components. It has received much attention due its attractive properties relationship normal distribution (which symmetric). Furthermore, coefficient variation (CV) commonly analyze within a dataset. In some situations, independent samples are collected from diff...

in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...
