Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
… and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead …
En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige
… Multiple linear regression was used to analyse the average speed, while Poisson regression was used in the analysis of the number of speed violations. An activated camera proved to cause a lowered average speed and fewer speed violations in three regions (Skåne, Mälardalen …
… includes contingency table analysis, multiple logistic regression, and Poisson regression. The results show that the demographic composition does not fully cover all the aspects of the Swedish population and some groups are less represented than others. The behaviour tends to …
en statistisk analys
… immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future. The other part of this thesis will inquire the matter how inclined immigrants are to become …
… in a stand was modelled based on stand categories using a zero-inflated Poisson regression. Sub-strate characteristics were the most important variables in species occurrence and therefore confirm the strong substrate specificity of Carbonicola anthracophila and C. myrmecina …
