    Attribute control charts for the Dagum distribution under truncated life tests
    (Springer, 2019) Gadde, S. R.; Fulment, A. K.; Josephat, P. K.
    In this paper, an attribute control chart for lifetime of the product follows Dagum distribution under number of failures before a specified time period is proposed. The sensitivity of the proposed chart is studied using the average run length (ARL). The tables are presented for all shift sizes, different sample sizes, various values of shape parameters and specified ARL and shift constants. An application of the proposed control chart in industry for monitoring of non-conforming items is illustrated with simulation data.

    Bootstrap confidence intervals of CNpk for exponentiated Fréchet distribution
    (Springer Nature, 2019) Gadde, S. R.; Rosaiah, K.; Mothukuri, S. B.
    Confidence intervals for process capability index using bootstrap method (Chen and Pearn, Qual Reliab Eng Int 13(6), 355–360, 1997) are constructed through simulation assuming that the underlying distribution is exponentiated Fréchet distribution (EFD). Parameters are estimated by Maximum likelihood (ML) method. Also obtain the estimated coverage probabilities and average widths of the bootstrap confidence intervals through Monte Carlo simulation. Illustrate the process capability indices for EFD using some numerical examples.
