1. Maximum likelihood theory and applications for distributions generated when observing a function of an exponential family variable
Sammanfattning : .... LÄS MER
2. Evaluation of climate model simulations by means of statistical methods
Sammanfattning : Evaluation of climate model simulations is a key issue within climate research. The statistical framework proposed by Sundberg et al., 2012, provides a theoretical underpinning of methods for evaluation of climate models by use of climateproxy data from the last millennium. LÄS MER
3. Regression methods in multidimensional prediction and estimation
Sammanfattning : In regression with near collinear explanatory variables, the least squares predictor has large variance. Ordinary least squares regression (OLSR) often leads to unrealistic regression coefficients. Several regularized regression methods have been proposed as alternatives. LÄS MER
4. Toward Sequential Data Assimilation for NWP Models Using Kalman Filter Tools
Sammanfattning : The aim of the meteorological data assimilation is to provide an initial field for Numerical Weather Prediction (NWP) and to sequentially update the knowledge about it using available observations. Kalman filtering is a robust technique for the sequential estimation of the unobservable model state based on the linear regression concept. LÄS MER
5. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model
Sammanfattning : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. LÄS MER
