Uni- and bimodal Weibull distribution for analyzing the tensile strength of Diss fibers
Journal of Natural Fibers, 2018 The present work considered several statistical distribution functions with the aim to critically analyze the strength data of natural Diss fibers. Besides the Weibull two-parameter distributions, three-parameter and bimodal Weibull were used. Kolmogorov–
