1. Classification models for high-dimensional data with sparsity patterns
Sammanfattning : Today's high-throughput data collection devices, e.g. spectrometers and gene chips, create information in abundance. However, this poses serious statistical challenges, as the number of features is usually much larger than the number of observed units. LÄS MER
2. Studies of tibial fractures using the Swedish Fracture Register
Sammanfattning : This thesis has two topics. First, the creation and application of the Swedish Fracture Register (SFR) is described. Second, a series of studies of tibial fractures based on data from the SFR follows. LÄS MER
3. Licence to drive : the importance of reliability for the validity of the Swedish driving licence test
Sammanfattning : Background: The Swedish driving licence test is a criterion-referenced test resulting in a pass or fail. It currently consists of two parts - a theory test with 65 multiple-choice items and a practical driving test where at least 25 minutes are spent driving in traffic. LÄS MER
4. Clavicle Fractures : Epidemiology, classification, treatment and outcome, with emphasis on displaced lateral clavicle fractures
Sammanfattning : The rate of surgical treatment for clavicle fractures has increased dramatically in the past 20 years, but the necessity for this remains obscure, particularly for displaced lateral clavicle fractures. The overall aim of the thesis is to acquire knowledge that may help guide treatment decisions for clavicle fractures, with an emphasis on displaced lateral fractures. LÄS MER
5. A novel approach to text classification
Sammanfattning : This thesis explores the foundations of text classification, using both empirical and deductive methods, with a focus on author identification and syntactic methods. We strive for a thorough theoretical understanding of what affects the effectiveness of classification in general. LÄS MER
