Kreditklassning av aktiebolag i Sverige, en logistisk regression

Predicting corporate failure is an increasingly important topic in the world of economics today. This paper, with the help of the credit ranking company Syna AB, aims to investigate a few different statistic strategies to do just that. This task is accomplished by using a data material of 250 000 Swedish companies divided into two subsamples. The first sample is used to develop the model and the second as a validation sample. The model developing sample holds 160 000 companies divided into five different subgroups based on size and age.

Återköp av aktier på den svenska marknaden : Hur påverkar utestående optioner sannolikheten för aktieåterköp?

I mars år 2000 blev det tillåtet för börsnoterade bolag att genomföra återköp av egna aktier i Sverige. En del kritiker hävdar att återköp kan användas till att påverka aktiekursen positivt, till förmån för bland annat optionsinnehavare. I denna uppsats har vi undersökt om antal utestående optioner till anställda ökar sannolikheten för genomförandet av aktieåterköp. För att ta reda på detta har vi undersökt data från samtliga bolag som var noterade på NASDAQ OMX Large Cap i Stockholm vid utgången av år 2007. Vi har analyserat datamaterialet med hjälp av enkel linjär regression samt logistisk regression.

Påverkan på TED- spread under den nuvarande finansiella krisen

The purpose of this essay is to test for significance between TED- spread and four different macrovariables, housing prices, Federal funds rate, Asset Backes Securities and mortgage volume. Multiple regression has been used to search for significance between the dependent and the four independent variables. Our data consist of quarterly reports from January 1998 to June 2008. Our conclusion is that all of the four variables show a significant relation with TED- spread. The model explains 76 percent of the variation in TED- spread..

Värdeförändring på butiksfastigheter och makroekonomiska variabler - en ekonometrisk studie av samvariation

The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the Multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.

Analys av kvalitet i en webbpanel : Studie av webbpanelsmedlemmarna och deras svarsmönster

During 2012, the employer of this essay carried out a telephone survey with 18000 participants and a web panel survey with 708 participants. Those who partook in the telephone survey were given a choice to join the web panel. The purpose of this work is to study the participants of the telephone survey and see if they reflect the Swedish population with regards to several socio-demographic factors. Also, we intend to investigate if the propensity to join the web panel differs for participants of the telephone survey with regards to various socio-demographic affiliations. It is also of interest to study if the response pattern is different for participants of the telephone survey that would like to join the web panel and those who reject.

Translationsnoggrannhet i läsningen mellan tRNA och mRNA : En analys av variationen i den maximala diskrimineringen d i initialselektion

The purpose of this thesis is to analyze the variation in the maximal discrimination of the interaction between cognate and a non-cognate codon and anti-codon (also called the d-value). The variation was analyzed with a Multiple regression model with the d-value as the dependent variable and with the codon position and the different mRNA and tRNA bases as independent variables. The result of the analysis not only confirmed earlier studies that the maximal accuracy was highest in the second codon position and lowest in the third codon position but we also found significant relationships and interaction effects..

PÅVERKAS DEN KOMMUNALA SKATTESATSEN AV POLITISKTSTYRE? : En strukturell analys av faktorer som avgör skatten i svenska kommuner

The aim of this report was to investigate which factors determine municipal taxes in Sweden.The aim was also to find out whether and how the forms of political rule are significant covariates. A Multiple regression analysis was performed using data from 289 municipalities. The analysis resulted in five dierent models, of which a model based on municipal grouping was found to be most satisfactory. In all of the models, there are effects from the form of political rule. The results indicate that socialist municipalities have higher tax rates than non-socialist.

En undersökning om fallolyckor med gångtrafikanter

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

VEM V?LJER VINSTEN? P?verkar den politiska f?rgen p? det kommunala styret hur mycket vinst som f?rs ?ver fr?n de kommunala bostadsbolagen?

Every year, Swedish municipalities transfer considerable amounts of profit from public housing companies to the owner municipality. Municipalities are allowed to do this, provided that the money is used to pay for certain purposes. But there are no legal repercussions if they do not comply. Not all municipalities choose to transfer profits. Based on partisan theory, this difference could be explained by the political governance of the municipality.

Spontaneous tumour regression

Complete tumour regression is the optimal outcome of cancer therapies. There are however types of tumours that naturally regress. Most of these are benign, dermatological and have an early onset in life. This literature study aims to elucidate the mechanisms behind spontaneous tumour regression. In Libechov Melanoblastoma-Bearing minipigs, an animal-model specifically bred to develop malignant melanoma, the tumours usually involute within three months.

Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island

This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.

Finansiering av småföretags internationalisering

AbstractAccording to several researchers finance is scarce, scarcer for small businesses than for big enterprises. Small and medium-sized enterprises, SMEs, that want to start exporting and sales or manufacturing abroad need capital to get ready. Which capital structure and financial costs do they have, and which forms of finance do they actually use for that purpose. New american research by Mansi, Reeb (2002) has suggested, that there is a positive connection between leverage and a negative one between financial costs and internationalization, and that a non-linear model better describes this connection.This study has gathered data in two ways: Through a questionnaire from 37 SMEs and balance sheet figures from totally 166 manufacturing SMEs. In order to examine, whether the company was active on the international market, 200 SMEs in south Sweden were asked, if they exported to, produced or sold on any other market than their home market.

Riksdagsvalet 2010 : En GIS-analys

Our social lives and where we live shape our choices in life. One of those choices is which party we vote for in the general election. The aim of this thesis is to see if there are any connections between the Swedish general election of 2010, demography, socioeconomic factors and geography. This is done with regression analysis and chosen variables. Another aim is to see where in Sweden the chosen variables aren?t enough to explain the results of the election.
