1. 11. Aspects of Moment Testing when p>n

   Författare :Zhizheng Wang; Thomas Holgersson; Miguel Fonseca; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-dimensional data; Asymptotic distribution; Kolmogorov condition; Monte Carlo simulation; Hypothesis testing; Skewness and kurtosis; Statistics Econometrics; Statistik;

   Sammanfattning : This thesis concerns the problem of statistical hypothesis testing for mean vector as well as testing for non-normality in a high-dimensional setting which is called the Kolmogorov condition. Since we consider mainly the first and the second moment in testing for mean vector and we utilize the third and the fourth moment in testing for non-normality, this thesis concerns a more general moment testing problem.
