    Sammanfattning : In this thesis, we model stochastic processes in time and space. We focus on the processes whose covariance structure is either changing over the time span, or depends on the location in space. We develop models that appropriately describe and analyze such data behaviors in various different fields including finance, economics and engineering. LÄS MER

  4. 3. Fertility, childcare and labour market : dynamics in time and space

    Sammanfattning : Paper [I] focuses on the effects of time and space dynamics on the description offertility in Sweden. Fertility is an important determinant of long-term populationgrowth and labour market conditions. The influence of time dynamics inpostponing or accelerating childbearing is assessed by considering two differenteffects of earnings. LÄS MER
