   Sammanfattning : Industrial Life Insurance (ILI) was introduced in Sweden in the beginning of the 1900s. Following models already used in the United Kingdom and the United States, this insurance was specifically aimed at manual labourers, promising pension savings and compensation to surviving relatives.

   Sammanfattning : This thesis presents studies of semi-Markov models for insurance and option rewards. The thesis consists of the introduction and six papers. The introduction presents the results of the thesis in an informal way.In paper A, a general semi-Markov reward model is presented. LÄS MER

4. 3. Testing for Periodicity and Trend in Long-Memory Processes

   Författare :Abdullah Almasri; Statistiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; temperature data.; sunspots data; wind speed data; varve data; Siegel’s test; Fisher’s test; periodogram; Fractional difference process; Discrete wavelet transform; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik; Wavelets; Statistik;

   Sammanfattning : This thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. LÄS MER

5. 4. Essays on Pensions and Information

   Författare :Dan Anderberg; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education Policies; Time-consistency; Education Incentives; Cross-subsidies; Redistribution; Moral Hazard; Disability Insurance; Public Pensions; Voting; Assets; Adverse selection; Private pension markets; Actuarial science; Försäkring ej försäkringsrätt S137 ;

   Sammanfattning : The first essay examines the outcome in a competitive private pension market characterised by adverse selection. In addition to using the private pension market, the consumers can save in a bequeathable asset. LÄS MER

7. 5. Hidden Markov models - Traffic modeling and subspace methods

   Författare :Sofia Andersson; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; operationsanalys; Statistics; operations research; subspace identification; state space representation; likelihood estimation; Poissonification; traffic analysis; hidden Markov model; Markov-modulated Poisson process; programmering; aktuariematematik;

   Sammanfattning : The main motivation for this thesis, however not the only one, is the search for models for traffic in telecommunication networks. Traffic characterization and modeling are of great importance in the analysis and dimensioning of communication systems. During the last decades we have experienced an explosive growth of our telecommunication networks. LÄS MER
