1. 1. Non-Linear Latent Variable Models: A Study of Factor Score Approaches

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Johan Vegelius; [2017]
   Nyckelord :Structural Equatio Model; Interaction Monte Carlo;

   Sammanfattning : Non-linear latent variable models are associated with problems which are difficult to handle in applied sciences. Four methods for estimating factor scores, with the purpose of estimating latent variable models with an interaction term, were investigated. LÄS MER

3. 2. En statistisk undersökning av transkriptionsnoggrannheten i kodande DNA-sekvenser i E.coli-bakterien

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Sofie Wiklund Froby; Johan Vegelius; [2015]
   Nyckelord :E.coli-bakterie; transkriptionsnoggrannhet; rrnC; thrA; DNA; RNA;

   Sammanfattning : Bacteria are exposed to evolutionary pressure to an extent unlike other organisms. This leads to a high degree of adaptation to its surrounding. This thesis investigates the degree of adaptation towards higher accuracy in the transcription of DNA to RNA in coding sequences in the DNA of the E. coli bacteria. LÄS MER
