Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.

Tidigare forskning har genom att studera alla tillgängliga företag eller företag medudda branscher exkluderade identifierat vissa nyckeltal som bra indikatorer påfinansiell kris. I denna studie undersöks om dessa nyckeltal även ger ettsamstämmigt resultat för en udda bransch. Med utgångspunkt frånbioteknikbranschen identifieras genom logistisk regression nyckeltalen korta skuldergenom eget kapital och avkastning på investerat kapital som indikatorer på finansiell kris.Avkastning på investerat kapital överensstämmer med tidigare resultat, medan kortaskulder genom eget kapital bör, för denna bransch, tolkas tvärt emot jämfört medtidigare studier..

Objective: In recent years there has been an increasing interest within the clinical (medical) science in measuring people?s health. When estimating quality of life, present practise is to use the EQ-5D questionnaire and an index which weighs the different questions. The question is what happens if the individuals estimate there own health, would it differ from the public preferences? The aim is to make a new prediction model based on the opinion of patients and compare it to the present model based on public preferences.Method: A sample of 362 patients with unstable coronary artery disease from the Frisc II trial, valued their quality of life in the acute phase and after 3, 6 and 12 months.

The aim of this paper is to analyze aid, grouped into sectors, and its effect on growth in developing countries, to find out which type of aid has had the most positive effect on growth. We compiled a regression analysis based on panel data over 81 developing countries from 1975-1999. In our first regression we considered and group countries by institutional quality, in the other we considered and group countries after regional differences. As a measure on institutional quality we used the KKZ-index. The principal aim of this paper was to find out what kind of aid is the most efficient in its influence on growth in LDC?s.

På sistone har allt mer kritik riktats mot forskning inom klassificering. Trots att forskningen har resulterat i en uppsjö av klassificeringsmetoder finns det de som menar att den har varit ett misslyckande och pekar på det faktum att ingen klassificeringsmetod anses vara systematiskt bättre än den andra eller ens rena gissningar. Detta leder till att valet av klassificeringsmetod i många fall vilar på individuella preferenser snarare än på vetenskaplig grund. Enligt litteraturen bottnar detta faktum i ett underliggande samband mellan det optimala valet av klassificeringsmetod och egenskaperna som karaktäriserar datamaterialet.Uppsatsen tar avstamp från denna problematik och syftar till att undersöka kopplingen mellan det optimala valet av klassificeringsmetod och datamaterialets egenskaper. Denna intention uppnår vi genom att tillämpa logistisk regression, elastic net och boosting tillämpat på klassificeringsträd på sex verkliga datamaterial med varierande statistiska egenskaper.Resultatet visar att den relativa klassificeringsförmågan varierar med datamaterialen.

Purpose: We have three purposes that will answer our problem questions. Our first purpose is to identify how diversification effects for investors changed between emerging markets and developed markets in the period 1996-2010. Our second purpose is to examine the two crises, IT and financial crisis, and if the correlations between these two crises have changed. Our third purpose is to examine to what extent the Swedish stock market was influenced by other markets in the period 1996-2010, the IT and financial crisis.Methodology: The method is based on an analytic model consisting of two tools; Regression- and Correlation analysis. The Regression analysis will be used when investigating if a change in a foreign stock market affects a change on the Swedish stock market.

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.

No other conclusion can be drawn..

År 2007 är det högkonjunktur och arbetslösheten sjunker i Sverige. Fler väljer att läsa vidare på högskola och universitet och färre människor föds. En attraktiv arbetsplats vinner konkurrensen om den kompetens som finns. Arbetslivsinstitutet startade därför, tillsammans med Högskolan Dalarna, ett gemensamt forskningsprojekt 2001 som avslutades 2003. Projektet resulterade bla.

Betting under ordered forms has been around for a long time, but the recent increase in Internet betting and the large sums of money that are now involved makes it even more important for betting companies to have correct odds. The purpose of the essay is to calculate probabilities for outcomes of football games using a statistical model and to see if you can find better odds than a betting company.The data contains the 380 games from the 2004/2005 season and the variables form, head-to-heads, league position, points, home/away, average attendance, promoted team, distance and final league position from previous season. After performing an ordered probit regression we only find the variable ?form of the away team? to be significant at the 5 % level. We suspect the presence of multicollinearity and perform a VIF-test which confirms this. To fix this problem we perform a second ordered probit regression where a number of variables are combined to index variables. In the second regression we once again find only one significant variable.

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

Where is technology heading? And how will our behaviors towards these new innovations look? This project questions the direction of ?beyond smart? products, through scenarios within our everyday life. The work is both critical and speculative. Speculative in the sense that it is speculating in how a future scenario with ?beyond smart? products would look like.

This essay casts light on the quantitative aspect of the media representation of foreign news. The purpose of the essay is not only to describe the media representation of the countries of the world, but also to explain the representation out of structures that are mirrored by the mass media. Four hypotheses are stated that are operationalized in the research. These are treating four different factors that are believed to affect the representation, economy, geographical distance, cultural distance and the size of the population. A fifth hypothesis is stating that economy is the most influential of the factors.

The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..
