Modified likelihood approach for Wald-typed interval of the shape parameter in Weibull distribution

The Weibull distribution, widely used in lifetime analysis, is characterized by its shape parameter. We analytically derived Wald-type confidence intervals using standard and modified profile likelihood methods. Performance was assessed through a simulation study examining coverage probability (CP)...
