Two regression methods for estimation of a two-parameter Weibull distribution for reliability of dental materials

Abstract Objectives Comparison of estimation of the two-parameter Weibull distribution by two least squares (LS) methods with interchanged axes. Investigation of the influence of plotting positions and sample size. Derivation of 95% confidence intervals (95%CI) for Weibull parameters applicable in t...
