    • A Bayesian Lasso based sparse learning model 

      Helgøy, Ingvild Margrethe; Li, Yushu (Journal article; Peer reviewed, 2023)
      The Bayesian Lasso is constructed in the linear regression framework and applies the Gibbs sampling to estimate the regression parameters. This paper develops a new sparse learning model, named the Bayesian Lasso Sparse ...

    • The Sibling Distribution for Multivariate Life Time Data 

      Helgøy, Ingvild Margrethe; Skaug, Hans Julius (Journal article; Peer reviewed, 2022)
      A flexible class of multivariate distributions for continuous lifetimes is proposed. The distribution is defined in terms of the age-at-death of m siblings. The expression for the joint density is derived using classical ...

    • Sparse Bayesian learning methods and statistical survival models 

      Helgøy, Ingvild Margrethe (Doctoral thesis, 2023-06-02)
      Med utviklinga av avanserte datainnsamlingsteknikkar og digitalisering, har omfanget av tilgjengelig data i ulike fagfelt auka enormt. Det blir difor stadig viktigare med effektive og nøyaktige algoritmar innan statistisk ...
