26. Analys av effektivitet hos en oddsmarknad medmultinominal logistisk regression och klusteranalys
Kandidat-uppsats, Stockholms universitet/Statistiska institutionenSammanfattning : Studien undersökte marknadseffektiviteten i oddsmarknaden för fotboll. Två statistiskamodeller formulerades och implementerades med tillhörande test för att undersöka omoddsmarknaden var svagt marknadseffektiv. Den första modellen var multinominal logistiskregression vilken utvärderades med ett klassiskt Likelihood-ratio test. LÄS MER
27. A comparative study on the unsupervised classification of rat neurons by their morphology
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : An ongoing problem regarding the automatic classification of neurons by their morphology is the lack of consensus between experts on neuron types. Unsupervised clustering using persistent homology as a descriptor for the morphology of neurons helps tackle the problem of bias in feature selection and has the potential of aiding neuroscience research in developing a framework for automatic neuron classification.

28. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.

29. Designing an Interactive tool for Cluster Analysis of Clickstream Data
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktionSammanfattning : The purpose of this study was to develop an interactive tool that enables identification of different types of users of an application based on clickstream data. A complex hierarchical clustering algorithm tool called Recursive Hierarchical Clustering (RHC) was used. LÄS MER
30. Illusion eller Verklighet? : En statistisk analys av relationen mellan e-förvaltning och demokrati
Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologiSammanfattning : The aim of this study is to examine the relationship between e-Government and Democracy. The first step in fulfilling this quest was to find indexes which appropriately quantify these very general terms. LÄS MER
