  • EMPIRICAL STUDY ON ROBUST REGRESSION ESTIMATORS AND THEIR PERFORMANCE 
    Sajesh, T.A; Raveendran, Lakshmi (Reliability: Theory & Applications,, 2023-08)
    Regression Analysis is statistical technique to model data. But the presence of outliers and influential points affect data modelling and its interpretation. Robust regression analysis is an alternative choice to this. ...
  • POWER GENERALIZED DUS TRANSFORMATION IN WEIBULL AND LOMAX DISTRIBUTIONS 
    Thomas, Beenu; Chacko, V. M. (ResearchGate, 2023-03)
