  • A simulation study on some confidence intervals for the population standard deviation 

    Abu-Shawiesh, Moustafa Omar Ahmed; Banik, Shipra; Golam Kibria, B. M. Golam Kibria (Institut d'Estadística de Catalunya, 2011)
    Article
    Open Access
    In this paper a robust estimator against outliers along with some other existing interval estimators are considered for estimating the population standard devi ation. An extensive simulation study has been conducted ...

  • Stress-strength reliability of Weibull distribution based on progressively censored samples 

    Asgharzadeh, Akbar; Valiollahi, Reza; Raqab, Mohammad Z. (Institut d'Estadística de Catalunya, 2011)
    Article
    Open Access
    Based on progressively Type-II censored samples, this pape r deals with inference for the stress- strength reliability R = P ( Y < X ) when X and Y are two independent Weibull distributions with different ...

  • Diagnostic measures for linear mixed measurement error models 

    Zare, Karim; Rasekh, Abdolrahman (Institut d'Estadística de Catalunya, 2011)
    Article
    Open Access
    In this paper, we present case deletion and mean shift outlie r models for linear mixed measure- ment error models using the corrected likelihood of Nakamur a (1990). We derive the corrected score test statistic for ...

  • Iterative beam search for simple assembly line balancing with a fixed number of work stations 

    Blum, Christian (Institut d'Estadística de Catalunya, 2011)
    Article
    Open Access
    The simple assembly line balancing problem (SALBP) concern s the assignment of tasks with pre-defined processing times to work stations that are arran ged in a line. Hereby, precedence constraints between the tasks ...

  • Generalized spatio-temporal models 

    Cepeda Cuervo, Edilberto (Institut d'Estadística de Catalunya, 2011)
    Article
    Open Access
    An important problem in statistics is the study of spatio-te mporal data taking into account the effect of explanatory variables such as latitude, longitud e and time. In this paper, a new Bayesian approach for analyzing ...
