  • Compounded Generalized Weibull Distribution- A Unified Approach 
    Chowdhury, Shovan (Indian Institute of Management Kozhikode, 2014-03)
    A uni ed approach is proposed in this paper to study a family of lifetime distribu- tions of a system consisting of random number of components in series and in parallel. While the lifetimes of the components are assumed ...
  • Distribution-free CUSUM Control Chart for Joint Monitoring of Location and Scale 
    Chowdhury, Shovan; Mukherjee, A; Chakraborti, S (Indian Institute of Management Kozhikode, 2014)
    Mukherjee and Chakraborti (2012) proposed a single distribution-free (nonparametric) Shewhart-type chart based on Lepage (1971) test statistic for simultaneously monitoring both the location and the scale parameters of a ...
  • On a Two-Parameter Discrete Distribution and its Applications 
    Chowdhury, Shovan; Mukherjee, Amitava; Nanda, Asok K (Indian Institute of Management Kozhikode, 2014)
    Here we introduce two-parameter compounded geometric distributions with monotone failure rates. These distributions are derived by compounding geometric distribution and zero-truncated Poisson distribution. Some statistical ...
  • A Phase-II Nonparametric Cusum Chart with an Application to Exchange Rates Data 
    Mukherjee, A; Marozzi, M; Chowdhury, Shovan (Indian Institute of Management Kozhikode, 2014-11)
    Recently, Chowdhury et al. (2014a) proposed a single distribution-free Shewhart-type control chart based on the Cucconi (1968) test statistic for monitoring shift in the unknown location and scale parameters of a process ...
  • Stochastic Comparisons of Parallel Systems of Heterogeneous Generalized Exponential Components 
    Kundu, Amarjit; Chowdhury, Shovan; Nanda, Asok K (Indian Institute of Management Kozhikode, 2014-10)
    Let X1;X2; : : : ;Xn (resp. Y1; Y2; : : : ; Yn) be independent random variables such that Xi (resp. Yi) follows generalized exponential distribution with shape parameter i and scale parameter i (resp. i), i = 1; 2; : ...
