PARAMETRIC AND NONPARAMETRIC PORTMANTEAU TESTS FOR LACK OF FIT IN TIME SERIES MODELS: A COMPARATIVE STUDY
(06-2 , Master Thesis)Several diagnostic tests for the lack of fit time series models have been introduced using parametric and nonparametric portmanteau tests. Some tests have been proposed based on the asymptotic distributions. Others are ... -
IMPROVED INFERENCE FOR THE SCALE PARAMETER IN THE LOMAX DISTRIBUTION BASED ON ADJUSTED PROFILE LIKELIHOOD FUNCTIONS
(06-2 , Master Thesis)In this thesis, we consider improving maximum likelihood inference for the scale parameter of the Lomax distribution. The improvement is based on using modification to the maximum likelihood estimator based on Barndorff-Nielsen's ... -
PREPARATION AND CHARACTERIZATION OF POLYMERIC FOAMS FOR REMOVAL OF FREE OIL FROM WATER
(06-2 , Master Thesis)Development of polymeric foams for removal of oily pollutants (spills) from water is a key target of this thesis. Pollutants occur in the form of free oil (floating on the water surface) or oil/water macroscopic, non-stabilized ... -
