Analysis of Loan data and relationship with various factors
Introduction
As we all know the history of loans as old as the history of money. Earlier there used to be different mechanism of lending money and recovering it. In simple terms it was the process in which the people who have more money than they required used to give money to people who didn’t had enough. Over the years with the evolution of economics the loan process became extremely important for the people who made business out of it. They used to give loans to people who needed it. But there was always a risk of person defaulting on the loan. For this reason before giving the loan the companies analyses various factors such as the credit history of the borrower, loan period, interest rates, income source etc. in order to prevent any default. In this assignment we are trying to find relation between the interest rates and the various factors like amount, loan length, debt to income ratio, monthly income, FICO score etc. Methods

Data Collection
The data was collected from the link https://spark-public.s3.amazonaws.com/dataanalysis/loansData.csv provided on the coursera page. The data was downloaded on 14th February 2013 using R software Exploratory Analysis

Exploratory analysis on the data was done by examining table and plotting the data. The exploratory analysis was used to clean the data and determine factors to be used for the linear regression model. The cleaning of data involved removing inconsistent metrics like year/years, removing percentage signs an converting from factors to numeric for the purpose of regression analysis. Statistical Modelling

A standard model of multiple linear regressions was built using the R software to check and determine the relationship between the outcome variable and the various factors. Coefficients were calculated and the significance was checked using the P value. The R square value and ANOVA table construction helped in interpreting the result. The final...

Introduction
The concepts of sustainability began to form in the 1970s when there was much discussion at various forums concerning economic development and its impact on the environment and humankind. There was widespread acceptance that economic development should be sustainable, that is, having little negative impact on the earth and humans (especially, our future generations). At present, many consider this to be a theoretical ideal. In reality, sustainable development cannot be achieved within a short time frame. More likely, it is a long-term goal.
Corporate sustainability reporting originated in the early 1990s, when some companies, mainly large multinationals in many countries, began to disclose, in their annual reports, the environmental and social impacts of their operations. In the mid- 1990s, it became common for companies to report on their social performance(Dillard 2004).
Today, sustainable development is expected by society. Therefore, society also expects companies, governments, non-government...

...Introduction to DataAnalysisDataAnalysis Home
While working in lab this semester you will collect lots of data. If you are lucky your data will lead to a clear answer to the question you are investigating. At times, however, you will find your data ambiguous or, more interestingly, that something unexpected is hidden within the data. The modules on this site will guide you in exploring several important concepts in dataanalysis; these are:
the uncertainty inherent in any measurement and how that uncertainty affects your results
completing a preliminary analysis of your data by examining it visually and by characterizing it quantitatively
comparing data sets to determine if there are differences between them
modeling data using a linear regression analysis
examining data for possible outliers
Every discipline has its own terminology. If you are unsure about a term's meaning, use the link on the left for the On-Line Glossary. The data sets in these modules are Excel files. The How To... link provides reminders on using Excel. Each of these resources opens in a new browser window so you can keep them open and available while working on a module.

...Introduction
Our goal in this project is to carefully and accurately perform a regression analysis of the Ryanair share price to econometric parameters. We will examine several theoretically hypotheses and personally motivated hypotheses. We also will interpret the results of the study, by running appropriate tests relating to the assumed dataset. We choose Ryanair due to its recent success, especially given the downturn in the economy. It appears to go from strength to strength as its competition falters.
Having researched and consulted the model we should, we choose 4 independent variables to be used as regressors in our model. The variables we choose are as follows:
EasyJet Share Price
This is the daily adjusted closing share price for EasyJet, an airline company and a main competitor of Ryanair’s in the ‘Low Cost Carrier’ sector of the airline industry.
FTSE 100 Index
This is the daily closing price for the Financial Time Stock Exchange 100 Index.
Jet Kerosene
This is the daily closing spot price for U.S. Gulf Coast Kerosene Type Jet Fuel. This is the type of fuel that airlines use and we thought it would be a better indicator of Ryanairs fuel consumption that just a normal crude oil price.
Crude Oil Futures
This is the daily closing futures price for the NYMEX Crude Oil futures. Since Ryanair have in recent years been hedging their fuel costs, we felt that this would be an extremely relevant variable to include in our regression. Each daily...

...DataAnalysis Report
Case Study – Computers R Us
Executive summary
This report aims to figure out two basic questions, current consumers’ satisfaction and strategy that would be most potent to increase overall satisfaction. At the beginning, a survey of three parts was designed and conducted across different age groups.420 samples were collected and coding and editing of a variety of data ensued. By resorting to hypothesis test, regression model, this report found out that current consumers’ satisfaction level is much lower than management expected and two gender groups show significantly different satisfaction .Also, consumer satisfaction was similar across five age groups. In respect of determinants of consumer satisfaction, satisfaction with response time, satisfaction with the level of advice from staff at call centre, satisfaction with the level of communication and satisfaction with loyalty rewards program from consumers are all key contributors while only satisfaction with the level of communication has positive relationship with overall consumer satisfaction. Thus, in order to make effective strategy to improve overall satisfaction, Computer R Us should increase methods of communication.
Introduction
Computer R Us, whose main business focuses on manufacture and retail of computers, recently set up a division called Completecare. This division offers consumers service and repair for its computers. However, in its everyday...

...Introduction:
Dataanalysis is an attempt by the researcher to summarize collected data either quantitative or qualitative. Generally, quantitative analysis is simply a way of measuring things but more specifically it can be considered as a systematic approach to investigations. In this approach numerical data is collected or the researcher transforms collected or observed data into numericaldata. It is ideal for finding out when and where, who and what and any relationships and patterns between variables. This is research which involves measuring or counting attributes (i.e. quantities). It can be defined as:
“The numerical representation and manipulation of observations for the purpose of describing and explaining the phenomena that those observations reflect is called quantitative analysis”
Quantitative analysis gives base to quantitative geography and considered as one of important parts of geographical research. As, subject matter of quantitative geography is comprehended by the following key issues:
Collection of empirical dataAnalysis of numerical spatial data
Development of spatial methods for measurements, theories and hypothesis
Construction and testing of mathematical models of spatial theory
Concisely, all above mentioned activities develop understanding of spatial processes. Quantitative...

Introduction
The purpose of this survey was to investigate the cognitive effects of stimulant medication in children with mental retardation and Attention-Deficit/Hyperactivity Disorder. Twenty four children were given various dosage of a drug a placebo and 0.60mg/kg. Variable descriptions are kind of drug taken and the number of correct responses after taking of the drug. They were on each dose one week before testing. This sample obtained from the preschool delay task of Gordon Diagnostic System (Gordon, 1983). However, does higher dosage lead to higher cognitive performance?
