The Swedish Transport Agency has for a long time collected data on a monthly basis for different Variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few Variables in which Holt-Winters method has been adapted.

Agency theory describes the conflict of interest between the principal (stockholders) and the agent (CEO). Aligning the incentives of executives with those of the owners is the most direct way to mitigate the agency problem. If there is no meaningful link between CEO compensation and company performance, it is doubtful that the large sums of assets in public corporations are being managed efficiently. In theory the solution is simple reward the CEO when shareholders wealth increases. The purpose of this paper is to investigate if there is a relationship between company performance and CEO compensation among Swedish companies, in materials and information technology industry.

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable.

This study examines if there are any behavioural differences in-store between consumers who choose a healthy product and consumers who choose a regular product. 540 observations were conducted were different Variables were studied. Tthe results indicate that there are some Variables that show a significant difference in behaviour at the point of choice between consumer who choose healthy products and those who choose regular products..

Previous research has shown that there is a relationship between trust and organizational commitment. Our research questions were if the three trust-Variables ability, benevolence and integrity predict organizational commitment differently. Further we examined if the length of employment affected the relationship between benevolence and organizational commitment. Due to the fact that past studies has shown that benevolence develop during a longer period of time than do the other trust-Variables. We made a survey using questionnaires (n=50) in a ?caretaking facility? and using a multiple regression analysis we found that ability was a significant predictor (p=0.032) for organizational commitment.

This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input Variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input Variables are identified and analysed.

The discussion regarding international aid tends to be highly debated for long periods of time. Some individuals are very positive towards aid and some individuals are less positive towards aid. This study aims to broaden the understanding of the aspects behind that. The previous research tends to focus on aid allocation within the EU, or which macro factors could influence which donor countries give to which recipient countries. This study aims to add to the research with which aspects at the individual level can influence the individual's attitude towards international aid from the EU.

Thesis purpose: The aim of this paper is to extend the knowledge of what influences the purchase decision of functional food in the store. By applying the M-R model in a new setting - the dairy department in grocery retailing in Sweden - and adding Variables related to health attitudes, the aim is to contribute to existing research concerning in-store purchase decision making and store environment as well as consumer attitudes. Methodology: This thesis employs a quantitative strategy with a deductive approach and data has been collected with questionnaires. Theoretical perspective: Environmental psychology serves as an overarching framework where, more specifically, certain aspects of store atmospherics and some Variables concomitant to health attitudes provide the theoretical base. Empirical data: The empirical data consists of customer purchasing a functional food product, Proviva, and this is contrasted with a test group, Bravo.

Commercial strategies are becoming more common in an increasing number of sports - Swedish golf is no exception. Previous research shows that new opportunities for non-profit organizations, to assign parts of their operations to a limited company, do not have any economic importance. The supplementary question arises why more golf clubs nonetheless choose to corporatize its activities? Is the purpose of commercial strategies generally linked to business- or sport-related success? This paper, containing two studies, aims to create an understanding of the underlying drivers of commercialization, and furthermore to quantitatively demonstrate how commercialization is reflected within Swedish golf in terms of strategy and marketing. Swedish golf clubs were categorized as more or less commercial, and examined based on business-related Variables such as communications, brand awareness and price discrimination, as well as sports-related Variables as success factors and success indicators.

This master thesis is an analysis of how the amount of health centers per inhabitant has changed since the Swedish government implemented a new health care reform in 2010. The reform implies a free choice of health centers in the Swedish regions and opens up the market for private firms. The purpose of the thesis is to study the effects of the different financing systems toward the health centers in the regions. The models are based on theories of the need of health care. Two of the independent Variables which are studied are income and age.

This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.

Habitat selection of migratory brown trout at the upper reaches of River Vindelälven, wasstudied in September during the pre-spawning period. The fish migrate from down- orupriver lakes for spawning in the river and data was collected by habitat mapping andradio-telemetry. Habitat selection of fish was analysed with preference curves andstatistical modelling, using the physical Variables; depth, stream velocity and streambedsubstrate. Preference curves were derived by comparing fish habitat use with their nearbyavailable environment while the statistical modelling aimed to answer three main questions.1) Do the trout have a specific preference of depth, water velocity and streambed substrate?2) Is there any difference in habitat selection between sexes? 3) Is there a shift in habitatselection over time? The preference curves indicated that trout favored water depths of 1-2m, velocity compositions characterized as glides (c.

Abstract During the last 15 years, the former ?really existing socialist? economies have undertaken an extensive transition process. In this paper the development, measured as GDP growth, is analyzed using Variables for economic policy. The analysis is both theoretical, taking as starting point current positions in academia, and econometrical with the linear regression model. We show that while economic policy Variables of inflation, economic freedom and institutional quality affect economic growth, the results are not only the ones predicted by the theory.

The aim of this thesis is to examine the properties of the municipalities in Sweden that influence the choice of being a certified Fairtrade city. The independent Variables which are used in the statistical analysis are municipal governance, local tax rate, whether there is an university and/or university college in the municipality, average income and higher education in the municipality. The Variables are examined by logistic regression. Since there are no statistical data on ethical procurement, this exogenous variable isn?t included in the regression.

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.
