Konsumentprisindex för kläder och skor 1986-2005 - Dekomponering och prognostisering

The essay initially intends to find adequate models to describe and forecast monthly data for the Swedish Consumer Price Index sub group Clothes and Shoes 1986-2005. The time series observations during 2006 are considered ?out of sample period? which is used to evaluate the forecasts. The purpose is to perform time series decomposition and to investigate and analyzethe seasonal pattern. The Box-Jenkins approach is used to find adequate ARIMA models.

Prediktion av bostadsrättspriser i Stockholms innerstad.

A frequently asked question in real estate marketing is at what time of the year it is optimal to invest or sell. The aim of the project was to answer this question and to generate a prediction model over real estate located in the centre of Stockholm that takes seasons into account. With acquired sales Statistics in Stockholm between 2010 and 2013 it was possible to perform a linear least square regression, also known as Ordinary Least Square (OLS), with describing qualities and season of sale as parameters. Statistical problems such as Multicollinearity and Heteroskedasticity have been taken into account when deriving the model. The result was a highly accurate prediction model indicating the profitability of investing in real estate during the summer and selling during the autumn..

BASEL III : En studie om baselregelverkets påverkan på den svenska banksektorn

Titel: Basel III ? En studie om baselregelverkets påverkan på den svenska banksektorn Nivå: D-nivå (30 Högskolepoäng) inom ämnet företagsekonomi Författare: Nour Reda 891029-xxxx, Johan Laryd 850131-xxxx Handledare: Per-Olof Bjuggren, Professor inom nationalekonomi; Economics, Finance and Statistics, Internationella Handelshögskolan.Louise Nordström, Doktorand inom nationalekonomi; Economics, Finance and Statistics, Internationella Handelshögskolan. Datum: Jönköping, Maj 2011 Frågeställningar: (i) Vilka behov finns för att det befintliga regelverket skall kompletteras? (ii) Hur kommer införandet av Basel III ändra kostnadsfördelningen mellan banken och dess kunder? (iii) Kommer införandet av Basel III leda till en stabilare finansiell marknad? Syfte: Det övergripande syftet med denna studie är att beskriva och undersöka Basel III:s påverkan på den svenska banksektorn. Metod: Författarna har inom studien använt en kvalitativ metod med en deduktiv ansats som tillvägagångssätt. De intervjufrågor som vi tagit fram har grundats på studiens tre frågeställningar. Respondenterna som intervjuats är personer som är ansvariga eller delaktiga i arbetet mot införandet av Basel III. Det har lämnats stort utrymme för respondenterna att kunna föra sina egna diskussioner för att vidare mynna till väldefinierade resultat. Resultat Resultatet av denna studie visar att de svenska storbankerna är positivt inställda mot införandet av Basel III och tror att det nya regelverket kommer bidra till en stabilare finansiell marknad.

Faktoranalys av EU: s strukturella indikatorer

This paper describes a factor analysis applied at the data of the European Union structural indicators. These are the official indicators for wealth and economic development in the European Union with main use to evaluate the outcomes of the year 2000 Lisbon goals for making the European Union the world?s strongest economy by 2010. The purpose of the data is to serve for comparing and ?learning by doing?-policies, but have, due to size and format, so far been hard to use for a good compare between member countries.

?Vi är till för kommuninvånarna? : En kvalitativ studie av musikavdelningen på Enköpings kommunbibliotek

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

Diffusionen av SOA

Uppsatsen ämnar ge en indikation om diffusionen av den tjänsteorienterade arkitekturen SOA, idag och dess framtida diffusion. Genom att operationalisera begreppet SOA med hjälp av litteratur har vi kunnat sammanställa en enkät i syfte att utföra en enkätundersökning. Genom det empiriska material vi samlat in har vi kunnat applicera detta i en modell för teknologisk diffusion, i syfte att ge en indikation i form av en graf för diffusionen av SOA. Resultatet visade på en överraskande hög spridning av SOA då sannolikheten för spridningen blev väldigt hög. Vi misstänker att vissa system- och programutvecklingsföretag tror sig ha spridit SOA utan att de gjort det.

Bootstrap som hjälpmedel att öka noggrannheten och bedöma precisionen vid probitregression, med tillämpning på hörselmätningar

In many biomedical contexts, e. g. when evaluating hearing disorders, the data obtained can be described as pairs (x1, y1), ?, (xn, yn) where x is a quantitative variable and y a 0/1 variable whose probability of taking the value 1 is a monotonic function of x. One way of analysing such data is to perform probit regression; thereby two parameters, b0 (= the constant) and b1 (= the slope) are estimated; the interest centres around m = -b0/b1, i.

Visualisering av marknadsstatistik

The purpose of this master thesis was to explore and develop prototypes for visualization of trade Statistics in a market surveilance application. In such an anapplication a large amount of information is processed. This information is then summarized and presented to the market surveillance staff. The practical part of this thesis was done at Scila AB in Stockholm. Three prototypes were developed based on modern visualization methods.

Svinnoptimering VTIS1

The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the Statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.

Projektledarens syn på Interaktionsdesign

Uppsatsen är ett resultat av en explorativ studie som undersöker projektledarens uppfattning av interaktionsdesign ur ett resursperspektiv. Detta görs genom en kvalitativ undersökning med projektledare för systemutvecklingsprojekt. Utifrån vilka det gjordes en nulägesrapport om hur vida resurserna som läggs på interaktionsdesign är adekvata. För att få en ytterligare aspekt på behovet intervjuades även en interaktionsdesignskonsult. Studiens resultat visade att det skiljer sig mellan olika typer av projekt hur vidare tillräckligt med resurser läggs ner på interaktionsdesign.

Sound Fence

To fence in pastures for sheep today is a major cost, especially because of the time required when using current methods. What takes most time is starting to fence off a new area, but to maintain a fence is also a continuous effort. The main function is to keep the sheep at the field.! !By interviewing and observing sheep farmers on how they work with fence today and what their problems was, I got a better understanding of the problem. Also looking at a number of other things like the context, Statistics on sheep farming, laws and competition mapping gave a wider image. But the most important part in my research occurred when I talked to experts about sheep behavior.

Volume and taper equations for Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L.) Karst.) and White spruce (Picea glauca (Moench) Voss) in Iceland

The aim of this study was to evaluate different types of volume and taper equations that can be used to predict single-tree stem volume and stem diameter at any given height along the tree stem for plantation grown Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L.) Karst) and White spruce (Picea glauca (Mounch) Voss) in Iceland. A number of published tree volume equations were tested and modified to predict the total stem volumes over bark but three logarithmic equations were taken for more in-depth analysis. Three taper equations were tested. Two variable-exponent equations (Kozak 1997, Kozak 2004) and one exponential equation described by Biging (1984). Data from a total of 617 sample trees were used in this study, collected from stands in various parts of the country and present different types of stands growing in different soil types and cover most of the site conditions suitable for forestry in Iceland.

Återanvändbara Use Cases inom telekomindustrin

Syftet med uppsatsen var att bidra med kunskap om hur Use Cases kan användas och omdet fanns en möjlighet att återanvända dem. Use Cases är ett av de mest användaverktygen för modellering, de beskriver en sekvens av en händelse som inskaffar ettmätbart värde. Use Cases fångar funktionaliteten i olika situationer. Vår studie varkoncentrerad på skillnaden mellan Use Cases så som vi uppfattat Rational UnifiedProcess (RUP) modell jämfört med Telecas återanvändbara Use Cases. Undersökningengjordes på telekomföretaget Teleca.

Självmord och självskadebeteende : en studie om självmord och självskadebeteende inom Svensk kriminalvård 2002- 2012.

During the period 2002-2012, 74 people committed suicide within the Swedish judicial system. During the same period of time 702 self-destructive actions and suicide attempts were reported. The purpose of this work was to investigate and illuminate the causes which are responsible for individuals committing suicide while in custody or in prison. The theory of this  work is an ethnographic study of a special social context. A study of literature, Statistics and earlier scientific research was used in this study.
